Conspectus method

• An overview, summary, a description of collection strength and collecting intensities

• Arranged by – subject– classification scheme– combination of either

• Containing standardized codes for collection or collecting levels and languages of materials collected


4

• Set of Conspectus reports, which include all appropriate collection information

• Collection descriptions may take a form of – unstructured textual documents– set of reports– structured open and standardized formats (database files)

The most libraries prefer database files Czech libraries prefer a set of reports

Preferred presentation of Conspectus model


5

Advantages of the Conspectus method

Detailed library collection descriptions• Collections and collecting patterns are described in

comparable terms• Conspectus values are accessible nationally (and

internationally) online or in paper format• Cooperative collecting or preservation policies can

be developed using the Conspectus as an instrument to map collection strengths


6

Disadvantages of Conspectus method

• A labour intensive method• A time consuming method• Based to a considerable extent on subjective

judgments• Application of conspectus method requires

conversion between classifications, e.G. To DDC; not all of the libraries' collections are classified in library of congress classification or DDC

• Conspectus categories and subjects may be unsatisfactory for certain subject areas– CCS is too detailed in some areas, and not

sufficiently detailed in others


7

Conspectus method applied in Czechia

• Discussion at the end of 1990s• Translation of documents concerning the

conspectus method • Serious doubts about its applicability for our

national archival collection among czech university libraries and other research and public libraries

• In 2000 the national library of the czech republic decided to carry out an evaluation of the strength of its collection in particular subject areas

• The collections of NLCR have been divided in three main branches: national archive collection, universal library collection, and study collection

Comments on Conspectus categorization scheme

• Is based on the shape of the north american academic world from the middle of the 20th century

• The shape of the scholarly world has changed since then• The context of our country and the surrounding central europe

is specific and different comparing with north america especially in subject domains such as– Education– Law– Politics, politology– European (small) languages, literatures– History– Auxiliar history sciences– Juvenile literature– Belles-lettres and literary criticism


16

Organization of information in Conspectus Categorization Scheme

• In conspectus categorization scheme information are organized by discipline (like in DDC or UDC)

• For example the topic “death” or documents containing information on death may appear in several conspectus categories, e.G. – 210 philosophy and theory of religion – 230 christian theology, christian doctrinal theology – 296 judaism – 297 islam – 393 death customs – 122-129 special metaphysics – 346 private law – 612 human physiology – 616 diseases. Clinical medicine


17

Conspectus Categorization Scheme used in Czechia

• Library resources are divided into 24 broad subject divisions

• Within these divisions subject is further divided into 584 conspectus categories

• And then into conspectus subjects – subject controlled terms – 31165 (topical terms – czenas)

• Original conspectus is based on LCC, DDC• UDC widelly used among czech libraries• Concordances between UDC-DDC necessary

18

Conspectus Divisions - the first hierarchical level

• Original WLN conspectus categorization scheme recomended by IFLA is respected

• The main objective of the first level is to provide an overview of library collections from subject´s viewpoint

• Among the libraries of the same type, e.G. National libraries of central europe, research libraries in humanities etc.

• The conspectus divisions are not tied to any universal classification scheme: it is not possible because the traditional classifications like ddc or udc are decimal; the whole knowledge is organized in ten main classes

19

First level of Conspectus Categorization scheme

• 1. Anthropology • 2. Biological sciences • 3. Performing Arts• 4. Business and economics • 5. Philosophy and religion • 6. Physical sciences • 7. Geography and earth sciences • 8. History and auxiliary sciences • 9. Music • 10. Chemistry • 11. Language, linguistics and

literature • 12. Library science, generalities

and references

• 13. Mathematics • 14. Medicine • 15. Political science • 16. Law • 17. Psychology • 18. Sociology • 19. Engineering and

technology • 20. Physical education and

recreation • 21. Art and architecture • 22. Education • 23. Computer sciences • 24. Agriculture


20

Differences between Conspectus Scheme, DDC and UDC at the first hierarchical level

• Conspectus divisions structure - 24 main subject categories - are more convenient for an inexperienced user; the important disciplines are enumerated at the first hierarchical level, e.G. Medicine, chemistry, mathematics

• One conspectus division contains data originating from various main classes of DDC/UDC, e.G. Conspectus division “business and economics” contains data from class 300/3 – social sciences and 600/6 technology

• In ddc and udc classifications, philosophy and psychology are included in one main class, the religion is located in a separate main class (2),

• In conspectus scheme, the religion and the philosophy are together in one division, the psychology forms a separate main division


21

Division 4 „Business and economics“ contains data from class 300/3 – Social sciences and 600/6 Technology

Division 5 „Philosophy and religion - are together in one division


22

Conspectus Categorization Scheme - principles of mapping

A decision has been accepted

• The first level must stay unchanged• At the second level all necessary information must be included

• The third level is created by systems of controlled terms used in czechia

• In the institutions that are responsible for subject analysis in their discipline, e.G.

• National technical library for techniques, technology and related subjects,

• National library of medicine for medicine and related topics, • Nlcr responsible for universal controlled system called

CZENAS


23

DDC UDC

• Universal system• Hierarchical structure• Ten mutuall exclusive

main classes• More supported • Relative Index Yes • More enumerative• Less meaningful

notation• Less faceted• Less flexible

• Universal system• Hierarchical structure• Ten mutuall exclusive

main classes, Class 4 is vacant

• Less supported• Relative Index NO• Less enumeratitve• More meaningful

notattion• More faceted • More flexible


24

DDC UDC• Notation: pure and

simple notation of Arabic numerals treated like decimal fractions

• Convention of the minimum of three digits

• Dot – punctuation sign - before the fourth digit

• Less meaningful notation

• Span of numbers – centered headings

• Notation: based on Arabic numerals plus other common symbols, arranged as decimal fractions

• Dot – punctuation sign - after the third digit

• More meaningful notattion

• Span of numbers


25

Facet Indicators in UDC 1• + / : used to combine separate numbers

• Ex.: 622+669 Mining and metallurgy • 592/599 Systematic zoology (equivalent to 592+593 ... +599) • 17:7 Ethics in relation to art

• = language• =111(02.053.2)... English language works - children`s books - subject

arrangement • Common auxiliaries

– (0…) common forms• (054)(44) French newspapers

– (1/9) place• (73)339.5.053 USA - trade balance

– (=…) ethnic groupings and/or nationality• (73)339.5.053 USA - trade balance

– “…” time• "04/14" The 5th to 15th centuries (the Middle Ages)

– -0 commonly recurring concepts -02 Properties, -03 Materials, -04 Activities, -05 Persons

• -037.52 Artificial mineral fibres. Glass fibres. Ceramic fibres • 347.96-055.2 Female lawyers


26

Facet Indicators in UDC 2• special auxiliaries-1/-9

– Literary forms in class 82 – Literature– 82-13 Epic poems

– Characteristics and details of machines, equipment, plant, processes and products in class 62

• 62-112 Machines according to type of construction .0 .03 Styles in Class 7

– 7.031Prehistoric art

' Alloys in Metallurgy, 669669.35'5'6 – Copper-zinc-tin alloys (combining 3 separate numbers)

The ability to join two (or more) numbers together to create a compound notation

Many compound concepts do not appear in the schedules, except as “Examples of combination”


27

UDC – DDC mapping

Main principles:

• To establish a connection between ddc conspectus category and udc conspectus category

• It means that only conspectus categories are mapped

• Subject headings and classification numbers entered in individual BIB records are not mapped

• The mapping is carried out in one direction only, from the UDC to the DDC


28

2nd hierarchical level of Conspectus Scheme • All mappings between DDC and UDC were realized at

this level only• Our intention was to create such a mapping tool

which enables both • To compare library collections at institutional,

national and – regarding conspectus scheme –international level as well

• To create such an organizing tool which is able to meet all (almost all) criteria of Czech libraries of all types


29

DDC in Czech Conspectus scheme

• To adapt the captions of the system to general end-users

• To support end-users understanding and web browsing, e.G.

• To add the name of a discipline when the DDC caption is not “complete”


30

Different point of view on European history and philosophy, unusual for Europeans


31

More Conspectus categories 1

• Subject areas heavily represented in Czech environment and missing in DDC Conspectus scheme are included in Czech Conspectus scheme, e.g


32

More Conspectus categories 2


33

Where is the Conspectus categorization scheme applied

The most important characteristic of the conspectus scheme - access to information resources through content characteristics - was used when creating and developing

The subject-oriented universal gateway (UIG – uniform information gateway),

Subject information gateways (KIV /library and information science/, MUS, TECH, ART) and

Topic map of the Czech National Library Collection

37

Topic map of library collections

• Can serve as an user friendly subject access for inexperienced library users and for those who prefer to get information on documents location directly and without the use of library catalogue.

• The main objective is to provide high quality services and improve information sharing. Topic map presents subject information in a systematic way and helps patrons use the portal trough a simple interface.

• In order to achieve this navigation and search function information resources are connected to the topics through the Conspectus categories data entered in bibliographic records.

Conspectus Categorization Scheme

Is not an ideal tool, but it is a very powerful and flexible tool which can be

• Used for organization of heterogenous information resources

• It can improve subject access• It can serve as navigation tool• It can serve as crosswalks between two

videlly used classification schemes DDC and UDC
