SUMMARY

At the beginning of the project, the microfilm unit of the National Archives of Trinidad and Tobago had no trained staff and only basic items of equipment in poor condition.

The main objective w a s to improve the output of the unit to ensure the long-term conservation of historical and other documents important to socio-economic development of the country, by providing security or access copies for consultation or reference.

The mission of the specialist has provided staff of the unit with on-the-job training in the proper use of the microfilming equipment which has been provided through the project.

In addition, guidelines on the techniques of microfilm processing, quality control monitoring, operation of the unit and equipment have been provided to ensure that the unit can n o w fulfil its role in the overall process of archival and records management .

I. Introduction

1. The following report contains the findings and guidelines on policy and procedures for the operation of the microfilm unit in accordance with Article 1, of the Consultant's Contract with the United Nations Educational, Scientific and Cultural Organization.

2. The instructions for project TRI/86/002 given to Terence llbury (referred to from n o w on as "the Consultant"), were to co-operate closely with the national authorities, and:

R e c o m m e n d steps which should be taken to upgrade the existing microfilm unit of the National Archives of Trinidad to ensure acceptable archival standards;

Develop guidelines on matters relating to policy and procedures for the operation of the unit;

Train the staff of the National Archives in the techniques of microfilming;

Demonstrate proper use and maintenance of equipment.

II General Situation

Archives

3. The Consultant identified a very large percentage of 19th Century material in a very fragile state, with brittle paper and evidence of infestation of the collection; mites and other insects were eating holes in the volumes.

4 . The newspaper collection w a s in a particularly bad condition and it w a s the decision of the National Archives that this collection of local papers should be given a top priority rating for its microfilming.

5. The Consultant also had the opportunity to inspect the archives held in the library at Scarborough. This collection w a s not as large as the collection in Port of Spain but w a s stored in controlled conditions, with temperature and humidity being monitored. It w a s , however, subjected to occasional power cuts. Held within this collection were the unattached Slave Lists covering the first half of the 19th Century.

6. This very important collection showed signs of severe deterioration. Infestation attack w a s noticeable and the paper w a s being eaten a w a y .

7 . In another collection there w a s evidence of poor fibre quality within the paper. This has the effect of heavy bleed-through of ink, rendering pages difficult to read.

1

This is obviously an important part of Trinidad and Tobago heritage. If action is not taken to preserve this collection, very soon a large proportion will be lost forever.

Staff and Training

The current staff of the National Archives is as follows:

Miss E Peters, Archivist (who w a s on annual leave). Miss B James, Deputy Archivist. Mr Boswell John (in charge of the microfilm unit) Mr Chandrabally Mohet, Assistant Photographer. Mr Peter Mejas, Conservation Officer, (attended the daily practical sessions the Consultant conducted).

Mr John had the benefit of completing a 4 month intensive microfilm training programme in the United Kingdom from October 1992 to February 1993 which w a s arranged through the British Council. He received practical training at the British Library and the National Library of Scotland.

The standard of work, knowledge and practical experience of staff of the microfilm unit at the National Archives w a s very poor and extremely limited.

The staff had been given instructions on h o w to use and operate the equipment by those responsible for the delivery and installation of the Film Processor, the M C G A . O . camera and the 1 6/35 Duplicator, but these instructions were not conducive to producing acceptable results, although it is possible that there is a case of misinterpretation of given instructions.

The processor was being operated at an incorrect speed, chemical temperature, dilution ratios and quantity were all wrong. N o consideration had been given to replenishment of chemicals and the staff had no knowledge of corrective actions to take in order to improve the quality of product.

R V 2 1 6 m m Camera - Filming w a s currently being carried out using this camera but film w a s being incorrectly exposed. Again, the staff had no knowledge of corrective action.

M C G A O Camera - None of the staff w a s competent to load film into the camera, or to determine correct reduction ratio and access optimum light levels to achieve the recommended negative background density.

16/35 Duplicator - The staff had attempted to undertake a small amount of film duplication but this had been stopped due to very poor results and lack of knowledge of h o w to improve the current situation.

The Consultant was a little surprised at the lack of practical knowledge Mr John displayed, although the Consultant n o w understands that he had not been able to

2

put much of what he was taught into practice due to the lack of essential

equipment at the Archives.

17. The Consultant found that Mr Mohet was a very practical member of the team who

could adapt easily to demands made of him. The Consultant began by inspecting

samples of the most recent work produced by the unit. It was found to be of very

poor quality with evidence that the film had not been processed to recommended

standards.

Existing Equipment

18. All equipment should be covered by a full preventative maintenance programme,

with servicing carried out where necessary by professional servicing agents. Only

when this is effected will there be any probability of the unit producing work to

recommended standards.

19. Film Processor - The processor, B R A Y , was operational but required spare parts.

The rubber squeeze lips were in urgent need of replacement. Because of the length

of time these items had been in the machine, they were the direct cause of

scratching processed film.

20. The Consultant realigned the rubber lips to a point where they were no longer

scratching the film, but would not recommend this to be permanent as the level of

chemical carry-over is unacceptable. These lips should be replaced at regular

intervals, weekly or bi-weekly as determined by film throughput.

21. The Consultant was very concerned that if any major fault arose with the processor

it would be very difficult to accommodate a repair, as there were no agents in the

Port of Spain area who could or would service this machine.

Cameras

22. M R D camera - The focussing projection light was not functioning. The projection

lamp mirror and camera head were covered in dust and dirt. The camera head

clutch was faulty thus affecting film transport, and rendering the camera unusable.

23. M C G Camera - When voltage tests were carried out a fault within the shutter

mechanism was identified. The camera also required a good clean.

24. R V 2 Camera - Exposure control settings were incorrect.

25. 16/35 Duplicator - The Duplicator functioned satisfactorily; no remedial action was

required.

3

Recommendations

26. The serious lack of most basic items of quality control equipment was very disturbing and, in the Consultant's opinion, must involve the purchase of the following items for the ultimate and continuing success of the unit:

a. Editing Bench - Complete with light box, film winders and ultrasonic splicer.

b. Microfilm Reading Machine - For quality control of first generation master negatives.

c. Densitometer - This should be a transmission type designed to measure visual diffuse density according to international standards.

d. Step Table - This is a length of film containing graduations of density. A calibrated step table is used as a standard in the calibration of a densitometer.

e. Microscope - The microscope used to read resolution shall have a magnification of 0.5 to 1.0 times.

Ill Training in Microfilm Techniques

Film Processing

27 . The Consultant decided to make film processing the first priority and soon discovered that the machine speed selected was processing the film too quickly to allow it to dry when spooling up. A series of tests were conducted to select the appropriate machine speed that would allow the film to leave the processor dry. It was concluded that correct running speed should be set at No 4 .

28. The next obvious problem was that the film was not being fully developed or fixed correctly. The Consultant discussed with the staff of the unit the exact strength and volume of chemistry being used.

29. The problem was that ready-to-use chemical solution was being diluted, thus rendering it ineffective. The volume of chemicals displaced in the developer and fixer tanks was recommended at 2.8 litres. The staff of the unit were only putting in 500 m/l.

30 . Clearly the chemicals and volume were drastically below the recommended levels. The tanks were filled to the recommended level and chemistry was not diluted. Chemistry temperature was then set at 35°c.

4

31. A full range of camera tests were exposed and processed. The results were a vast improvement to what w a s being processed previously, but were still not quite right. S o m e chemical fogging w a s evident.

32 . The Consultant instructed the staff to carry out a second camera test and dropped the developer temperature to 30°c. The results were satisfactory giving good background density, with no chemical fog. This represented a major step forward to the quality and performance of the unit as a whole.

33. It w a s soon evident that no thought had been given to replenishing the chemicals w h e n film had been processed. During processing the action of the chemicals is lessened and must be replenished. It w a s established that a rate of 100 m/l of developer and fixer should be added after each roll of film processed.

34 . The Consultant suggested that a film processing diary be kept and all actions recorded. It would include the following:

1 ) Date 2) Number of films processed 3) W h e n replenishment w a s added 4) Machine speed and chemical temperature 5) W h e n fresh chemicals were introduced

This would enable staff to monitor and control processing helping to ensure consistent results.

Cameras

35. The Consultant's next task w a s to demonstrate correct use of the cameras. The unit has three cameras - a M R D Kodak, M C G Kodak and a R V 2 1 6 m m , also Kodak. All cameras are of the planetary type. Before the Consultant began to explain correct camera procedures the opportunity w a s taken to demonstrate general maintenance skills.

36. M R D Kodak Camera - The focussing projection light on the M R D camera was not functioning. The staff were shown h o w to remove the cover to identify the problem. It turned out that just general cleaning was required.

37. The projection lamp is reflected through a mirror. This w a s so covered with dirt and dust it w a s severely restricting the light. However it only required cleaning.

38. The camera head w a s inspected, again there was an accumulation of dirt and dust, all these areas were cleaned. The Consultant demonstrated h o w to remove the camera head from its mounting and inspected the lens. This and the surrounding area were thoroughly cleaned.

39. Another problem identified within the camera head that affected the film transportation eventually transpired to be the clutch. This is a major fault that can

5

only be rectified by a fully trained service engineer. The Consultant contacted Harriman Limited to send out a service engineer to repair the fault and was informed that an estimate had been sent to the National Archives over a year ago for the same fault, but had not been taken up. Harriman Limited will send another estimate.

40. It is essential that this camera be repaired as it cannot function in its present state.

41. M C G Kodak Camera - The M C G camera w a s inspected and again, just required a good clean. A build up of dirt and dust w a s removed from all areas within the camera head lens area.

42. The Consultant demonstrated h o w to use and operate the M C G camera starting with the correct procedure of film loading, all staff members practiced this and after the session were fairly proficient.

43. Selecting reduction ratios to accommodate differing sizes of material and correct positioning of the original on the copy board was demonstrated and again the staff spent time practicing this technique. Each member of the archives staff w a s given a volume, all of differing sizes and asked to select the reduction ratios and correctly position the volume on the base board of the camera. After some prompting all of them were able to carry out this task.

44. Camera tests were then carried out for optimum background density. After processing a fault was evident within the shutter of the camera, every frame had a fogging mark at the top edge of the film. Again, the Consultant contacted Harriman's w h o could not visit the archives until 6 December 1993. Both the 3 5 m m cameras were n o w awaiting repair.

45. R V 2 1 6 m m Kodak Camera - The R V 2 camera w a s in working order and had recently been used by the archive staff. However, film background density from this camera w a s unacceptable. The Consultant enquired whether or not the exposure control had been moved to increase the exposure.

46. The archive staff had no knowledge of where it w a s or h o w to operate it. The adjustment screw w a s positioned at the rear of the camera revealing a scale of 1 -7 . A test w a s made by moving the screw to all the positions along the scale. After processing the test was examined and it w a s decided that the optimum negative density was at the 1.5 position on the scale.

47. 16/35 Duplicator - The archives staff were next instructed on the basic principles of duplicating. The important points to remember when duplicating is that film must be emulsion to emulsion when loading and duplicating; and that correct light setting must be selected to accommodate different negative densities. It was explained that direct negative duplicate film requires a higher number setting, around 87.5, whereas silver duplicate film would require an average setting of 50.

6

48. The staff at the archives began to link up the duplicator and started to run tests.

Results were acceptable and a small duplicating programme was initiated to

complete a request for the Prime Minister's Office. Of the first 3 rolls completed,

the quality of the copy was very good.

Testing Equipment

49. Because of the complete lack of any basic testing equipment at the archives, the

consultant contacted Harriman's to enquire if permission would be granted to bring

along the micro unit staff to use the Densitometer to assess negative background

density of film.

50. Harriman's were delighted to accommodate. The Consultant demonstrated proper

use of the equipment, and the archive staff were then instructed in its use.

Training Seminar

51. The Consultant was invited, along with Miss James, to attend a meeting with Mr

Wilkinson, Permanent Secretary at his office in Independent Square. Mr Wilkinson

wanted to know how the Consultant viewed the current situation at the National

Archives. The Consultant said that he would teach the staff of the microfilm unit

the basic fundamentals that would enable them to produce reasonable quality

microfilm but could not improve the current situation until essential items of

equipment were purchased.

52. The Permanent Secretary then asked the Consultant if he would be agreeable to

give a talk on the subject and said he would invite other Library staff from the

various libraries in the Port of Spain area. The Consultant gave the talk entitled

Microfilm as an aid to preservation in libraries at the National Archives. A lively

questions and answer session followed, involving about 25 people.

IV Guidelines Relating to Policy and Procedure

53. A stock of spare parts for the equipment should be held at the archives. The

consultant left a list of recommended spare parts at the microfilm unit. These

items should be re-ordered as they are used.

54. A system should be in place to re-order consumables when a certain minimum level

of stock items has been reached to ensure the unit does not run out of vital

supplies.

55. The Consultant agreed to write out guidelines on procedures to be adopted when

setting up the processor in the morning and closing down at the end of the day,

as well as guidelines for all cameras and the 16/35 duplicator. These are step-by-

step instructions to act as an aide memoire for the staff operating the unit. These

instructions were written in the form of a manual and left at the microfilm unit.

7

56. The management of the National Archives of Trinidad should not (as far as practical) allow staff to work on the archives, unless they are trained for the job, as described in section IV "Guidelines relating to Policy and Procedure".

57 . The following guidelines are to assist the management of the National Archives by explaining what is required of staff in each area, helping to identify skills and may be used w h e n employing staff, or designing training programmes.

a. Creating master negative microfilm by filming items from the collections

Understanding the operation of the camera.

Understanding exposures and light settings to achieve standard densities from a wide variety of original material.

Ability to handle books to minimize damage during filming.

Legible handwriting to compile permanent information sheets to identify the film.

Dexterity, ability to do a repetitive job.

b. Processing Film to Archival Standards

Understanding h o w processors operate, including knowledge of chemicals involved and their interaction.

Ability to interpret test results and make adjustments to the processing chemistry to ensure constant standards of film development.

Ability to work alone, often in the dark.

c. Checking Archival Negatives

Meeting standards for density control to ensure that the film is a true and accurate copy of the original.

Understanding operation of equipment used to check density, contrast and resolution.

Good knowledge of standards, usually gained through camera operation.

Ability to handle master negatives without damaging them, ability to splice and edit film.

Ability to check accurately film integrity i.e. spot missing pages, etc..

Communication skills, tact, judgement, attention to detail.

8

d. Duplicating from Archival Negatives

Understanding operation of machinery.

Ability to recognize changes in negative density to produce a copy to the standard required.

Ability to create records to enable subsequent film retrieval and to label boxes clearly for use in the search room.

Dexterity, legible, accurate handwriting.

e. Objectives of the unit

i. All film must be of uniform density throughout, of even illumination, good resolution and carry sufficient bibliographic information for the user. Background negative density should be in the range of 1.0 -1.4.

ii. Film processing must be controlled at all times with particular concern to machine speed and temperature of chemicals and washing water. Chemical activity should be monitored at regular intervals using pre-exposed controlled strips.

¡ii. Once initial tests have proved that satisfactory photographic results are obtained, it is important that conditions are kept as stable as possible to prevent variations in the quality achieved.

iv. The two main variable factors which affect the consistency of results are exposure and processing. A n y correction necessary to cope with different originals should be m a d e by controlling camera exposure and not adjusting the process, which should be maintained as nearly constant as possible.

v. Film should be tested to determine the residual thiosulphate content. The methylene blue test should be carried out to ensure the film is washed to archival standards. (The consultant c a m e to an agreement with the Manager at Harrimans that all methylene blue testing of processed film would be free of charge to the archives as long as the archives were willing to pay return postage to the U S A where testing is carried out.)

V Conclusions and Recommendations

Shortfall in Equipment

Conclusion 58. The archives require a number of essential items of equipment which are necessary

for the monitoring and assessment of work produced by the unit to meet archival standards. This w a s one of the reasons for the lack of any control over production.

Recommendation 59. Purchase equipment as specified by consultant in para. 26

Training

Conclusion 60. The standard of work being produced by the microfilm unit was of very poor

quality. Camera negatives were incorrectly exposed, film processing was particularly poor, machine speed, chemical temperature, levels and activity were all incorrect.

61. The staff awareness of problem solving, operating existing equipment and judgement of quality of product was very limited.

62. There was very little evidence of appreciation of international standards to achieve archival quality microfilm.

Recommendation 63. Ensure all new staff are trained in the use of the equipment; monitor quality of

results and arrange more training for existing staff if required.

Maintenance Contract

Conclusion 64. All existing equipment held in the microfilm unit is in urgent need of comprehensive

maintenance by professional servicing agents. Only when this is effected will there be any possibility of the unit producing work to recommended standards.

Recommendation 65. Purchase a regular maintenance contract with a professional servicing agent.

Use of Policy and Procedure Guidelines

Conclusion 66. The Archives needed assistance in identifying the qualities required of staff, and

training programmes for those staff.

10

Recommendation

67. The Consultant recommends that the National Archives give greater consideration to the qualities required of staff engaged in this type of work.

68. The management of the National Archives of Trinidad should not (as far as practical) allow staff to work on the archives, unless they are trained and qualified for the job, as described in section IV "Guidelines Relating to Policy and Procedure".

69. W h e n filming preservation material it is essential to G E T IT R I G H T F IRST T I M E , it may not be possible to repeat the operation due to the fragility of certain

materials. During the filming process of fragile material, there usually results the

loss of some of the original information, particularly with books containing brittle

paper, therefore the importance of having trained staff is vital to the job.

Upgrading Cameras

Conclusion

70. Upgrading the existing microfilm unit at the National Archives to enable it to achieve and maintain the quality of output of archival filming specified in existing international standards, requires a modest investment in new equipment and the dedication and co-operation of the staff of the unit.

71. The Consultant was asked about the possibility of replacing one of the existing 3 5 m m cameras in favour of a "Congress Camera" as this camera is used in a few national library establishments within the United Kingdom, and would undoubtedly enhance the quality of film produced.

Recommendation

72. The Consultant would recommend caution regarding any decision to purchase a Congress Camera. If the National Archives can be assured of prompt and professional maintenance service, with the guarantee of spare parts being made available without undue delay, then there is a case for its consideration. If however no such guarantee is forthcoming, the Consultant would not recommend its purchase.

Upgrading the Film Processor

Conclusion

73. The Film Processing machine is not user-friendly and is, when compared with alternative machines, cumbersome and difficult to operate.

Recommendation

74. The Consultant recommends that this machine be replaced with a K O D A K "Prostar". This machine has a number of advantages over the existing one being used at the National Archives.

11

75. The K O D A K "Prostar" is user-friendly, it is self-threading, does not require squeeze lips as the design of the film transport system incorporates this function within the processing racks, and if water temperature is within 30°C ± 5° , an archival wash is almost assured.

76. Another consideration is that the K O D A K Prostar can be serviced in Port of Spain.

Recording Experience

Conclusion 77. Training and experience are required to operate the Film Processor. Experiences

concerning the machine setting and results, both good and bad, should be recorded. The ability to refer to past experiences will help to make more accurate machine settings in the future.

Recommendation 78. Start a film processing diary, and record all machine settings and results.

Stock Control

Conclusion 79. Time was being wasted, or quality reduced when vital supplies ran out or when

spares were required.

Recommendation 80. The Consultant supplied a list of spare parts for the equipment held at the archives

and also prepared a list suggesting the minimum number of consumables in stock for re-ordering.

12
