In 1987, Garfield introduced the concept of "citation classics" for the best-cited articles. An analysis of top-cited articles coming from journals in the field of occupational medicine (eg, Occupational and Environmental Medicine, Scandinavian Journal of Work, Environment & Health) has not yet been reported. The purpose of this study was to assess whether or not such citation classics exist in this field and to analyze their characteristics. METHODS: The most frequently cited articles published in the five major journals in occupational medicine were identified using the database of Science Citation Index Expanded. The data were obtained by searching one year and one journal at a time. All of the articles cited more than 100 times were collected and analyzed. RESULTS: Among the 15 553 articles published by the five journals since 1949, only 85 articles had been cited more than 100 times. The oldest had been published in 1950 and the latest in 1997. The United Kingdom contributed 28% of the citation classics and the United States or Sweden produced 19%. The most cited article had been cited 979 times. The main topics of articles were metabolism, occupational neoplasms, and work-related musculoskeletal disorders. CONCLUSIONS: Since the 1980s, Scandinavia and the United States have taken the leadership in the publication of citation classic papers. Nevertheless, according to the level of citations, the influence of literature published in occupational medicine journals remains limited. Citation classics in occupational medicine journals.

The objective of this work is to propose a categorization algorithm to classify a set of scientific articles indexed with the MeSH thesaurus, and in particular those of the MEDLINE bibliographic database. In a large bibliographic database such as MEDLINE, finding materials of particular interest to a specialty group, or relevant to a particular audience, can be difficult. The categorization refines the retrieval of indexed material. In the CISMeF terminology, metaterms can be considered as super-concepts. They were primarily conceived to improve recall in the CISMeF quality-controlled health gateway. METHODS: The MEDLINE categorization algorithm (MCA) is based on semantic links existing between MeSH terms and metaterms on the one hand and between MeSH subheadings and metaterms on the other hand. These links are used to automatically infer a list of metaterms from any MeSH term/subheading indexing. Medical librarians manually select the semantic links. RESULTS: The MEDLINE categorization algorithm lists the medical specialties relevant to a MEDLINE file by decreasing order of their importance. The MEDLINE categorization algorithm is available on a Web site. It can run on any MEDLINE file in a batch mode. As an example, the top 3 medical specialties for the set of 60 articles published in BioMed Central Medical Informatics & Decision Making, which are currently indexed in MEDLINE are: information science, organization and administration and medical informatics. CONCLUSION: We have presented a MEDLINE categorization algorithm in order to classify the medical specialties addressed in any MEDLINE file in the form of a ranked list of relevant specialties. The categorization method introduced in this paper is based on the manual indexing of resources with MeSH (terms/subheadings) pairs by NLM indexers. This algorithm may be used as a new bibliometric tool. A MEDLINE categorization algorithm.

This complicates the follow up of literature for specialists in this field. On the basis of Medline and the impact factor, this diversity was assessed, and a cost effective method for selecting the most pertinent journals in the practice of occupational health was proposed. METHODS[---]A Medline search identified all the articles published in 1998 with occupational diseases or occupational exposures as the main topic. These articles were classified based on the journals in which they appeared. The journals were then compared according to their subject area, the number of articles that were published in the fields studied, and their impact factor. RESULTS[---]The search retrieved 2247 articles, published in 577 different journals in 1998. Each journal published between one and 105 articles during this period (mean 3.89). However, only 1.4% of the journals accounted for more than 25% of the total articles published. More than half of the articles were published in journals dealing with general practice or medical specialties other than occupational health. Only 66% of retrieved journals had an impact factor, and more than 80% of the articles were published in journals with an impact factor <2. CONCLUSION[---]Simply following up occupational health journals is not sufficient to meet the requirements of the occupational health professional. Moreover, the use of the impact factor cannot be considered as a reliable research tool to assess follow up. Two lists of eight and 38 journals were thus set up. They permit a literature coverage of 27% and 52% respectively in the specific fields studied, and this seems to be the optimal compromise between time and literature covered. Lastly, practical procedures are suggested to follow up literature and obtain abstracts from selected journals on the internet. 10.1136/oem.57.10.706 How to select publications on occupational health: the usefulness of Medline and the impact factor JF Gehanno B Thirion doi:10.1136/oem.57.10.706 Occup Environ Med, Vol. 57, No. 10.
