Low priced shareware packages may be adequate for those whose main need is to index a collection of articles read in journals. Those who search the literature electronically will need a package able to import mass data. Pro-Cite is set up for bibliographic functions only, but Reference File and Notebook II can be used to index any kind of collection, with Reference File having the advantage of being memory-resident. Other reference filing databases being considered for purchase could be measured against those reviewed here.
