The software programme Reference manager serves as a personal database for bibliographic references within a restricted field, especially journal articles (with abstracts). Yet it is more than a digital card index. References can be retrieved via author name, keyword, title word, year of publication, or name of periodical. During the preparation of a manuscript by means of a word processor, references can be simply indicated by one or more of these characteristics. Later Reference manager transforms these provisional references automatically into a bibliography and text references, according to the style of the journal in question. The personal database does not have to be built through laborious copying, but can be captured from Medline databases. Updating with recent references is possible by means of bibliographic services such as Current contents or Reference update.
