Medline
Decision whether or not to index a journal is made by the Director of the National Library of Medicine (NLM), based on considerations of both scientific policy and scientific quality
The Literature Selection Technical Review Committee (LSTRC) reviews journal titles and assesses the quality of their contents (incorporating advices of outside experts in the subject area)
As a result of these reviews, currently indexed titles may be dropped and new titles added
Medline criteria
Scope, coverage, audience, and quality of content predominantly on core biomedical subjects, targeted to the
health professions; scientific merit is the primary consideration in selecting journals for indexing
Types of content1. original research2. original clinical observations with analysis and discussion3. analysis of philosophical/social aspects of health sciences4. critical reviews5. statistical compilations6. descriptions of evaluation of methods or procedures7. case reports with discussions
Medline criteria
Production quality quality of layout, printing, graphics, and illustrations
Geographic coverage “special attention is given to research, public health,
epidemiology, standards of health care, and indigenous diseases”
journals will generally not be selected if contents are already well represented or if they are being published for a local audience
Foreign language journals same criteria as for those written in English however, the majority of published articles should contain an
English-language abstract
Medline criteria
Quality of editorial work
objectivity, credibility, and quality of contents
• information about the methods of selecting articles, especially on the explicit process of external peer review
• statements indicating adherence to ethical guidelines
• evidence that authors disclose financial conflicts of interest
• timely correction of errors
• explicit responsible retractions as appropriate
• opportunity for comments and dissenting opinion
• advertising/commercial sponsorship should not raise questions about the objectivity of the published material
• sponsorship by national or international professional societies
How to get reviewed
The editor should (1) request a journal review by using the MEDLINE Review Application Form and (2) send the review issues (according to how frequently the journal is published) to the indicated address
It is also helpful to provide a subscription of the journal (no need to send CVs or letters to LSTRC members)
What if the journal is available only in electronic format? Request can be made after the journal has been accessible for at least six
months (necessary >20 articles published online)
Digital archive: MEDLINE wants to ensure that users will always have access to the full text of every article - permanent archive must be in PubMed Central or another site that is acceptable to NLM
Publisher must be able to submit data electronically in XML format

The application process
The review process
The LSTRC meets three times a year and ~190 titles are examined at each meeting Requesters are not informed of the specific date Notification is sent to the editor weeks after the
meeting
Rating scores range from 0 to 5 Scores 3.75 or greater required to be selected for
indexing Overall, about 20% to 25% of the titles reviewed
are selected for indexing
If the journal is not selected LSTRC conducts re-examinations upon request
Titles may be re-examined after a minimum of two years following the first review date
After subsequent reviews, titles may be re-examined after a minimum of three years following the prior review date
Intervals should allow editors and publishers time to implement improvements to their journal
It also guarantees that the majority of the LSTRC membership will have changed by the time of the next review
If the journal is selected
When will indexing begin? If a journal is in its third volume or less when
selected, MEDLINE will index the articles in all volumes
If in its fourth year or more, indexing will begin with the current year (articles in earlier volumes will not be retrospectively indexed)
Congratulations! - What about other indexation databases?
Web of Science®
Includes Science Citation Index Expanded™ Social Sciences Citation Index® Arts & Humanities Citation Index®
Annually reviews over 2,000 journal titles, and selects around 10% to 12%
Major criteria timeliness of publication (three consecutive issues) international editorial conventions (optimize retrievability of source articles) full text (or at least bibliographic information) in English peer review process each article should publish information on funding source
International diversity contributing authors editors and editorial advisory board members
Web of Science®
In 2008, 700 new regional journals were included Selection criteria: “same as for international journals although
citation analyses play a somewhat different role in the outcome”
Uniqueness of WoS inclusion process: analyses of citation data citations to the journal itself citation record of contributing authors
Other databases
