Citation research

Citation research can be used to find articles on a specific subject or to check bibliographical details.  It was developed commercially by Eugene Garfield at the Institute of Scientific Information (ISI) in Philadelphia in the 1950s:

The BMA Library does not subscribe to this index and BMA members should contact the library staff if they have enquires about citation information or check information about other libraries and organisations offering this service below.

The Web of Science is the online version which includes over 5,000 leading journals from many subjects.

Science citation index
It is based on the concept of citation indexing which links current and past publications. The Science Citation Index (SCI) indexes over 3 800 current journals and monograph series in science, medicine, agriculture, technology and behavioural science. The print index is updated bi-monthly.

It uses the intellectual link between a source document and the articles and books that it cites as references. Hence, the Citation Index lists the bibliographic references that are cited in current articles listed in the Source Index. It can be used to:

Find articles on a specific subject.
Find people or articles that have cited specific previously published articles.
Check bibliographical details.

Because the Science Citation Index draws on a range of grey and older literature, which is not covered in the main indexing databases, you can often trace obscure references in Humanities Citation Index, and Social Sciences Citation Index are also available.

These indexes index core publications but are not comprehensive and do not include all conferences, series, or books. Moreover, there is a time lag between the publication of an item and its appearance in these indexes.

Impact factors
Impact factors measure the citation impact of a journal article with the research community. That is, they measure how many times articles in a journal have been cited in relation to the total number of articles in the journal. Library staff can undertake some research into impact factors for members.

They indicate the worthiness of a journal and as such are used by authors to ensure that they submit papers to a well-regarded journal, and by journals for marketing purposes. There are two tools for impact factors measurement:

Journal citation reports: these compare and rank journals with similar journals covering a subject discipline
University science indicators: these compare and rank universities by field or subject discipline.
