Subject strengths and weaknesses of four current-awareness services on diskette

This paper reports on a comparison of four current-awareness services on floppy disk: CURRENT CONTENTS ON DISKETTE--LIFE SCIENCES, CURRENT CONTENTS ON DISKETTE--CLINICAL MEDICINE, MEDICAL SCIENCE WEEKLY and REFERENCE UPDATE. The four differ considerably not so much in the number of journals as in the subject emphasis of journal titles covered. Like most bibliographic databases the area of particular interest to the individual or organization will dictate which of these services is the best choice. For many subspecialties the differences are too big to ignore; subject strengths and weaknesses are discussed in this article since many (end)users will depend on the advice of medical librarians.
