摘要:WIv TH the death of the Index-Catalogue, today's medical literature needs yet another new bibliographic control. What is needed is an analytic author-and-subject index to multi-author medical monographs. Single-author and dual-author monographs appear more and more to be sharing shelf-space with works by three or more authors, i.e. multi-author monographs wherein each chapter or section is credited to a separate author or authors. With the increasing complexity of the medical sciences this trend will doubtless continue, yet there is little or no bibliographic control over the multi-author monograph. The card catalog and the printed-fromcards book catalog continue excellent for the broad subject approach and a strictly limited number of author and added entries. But purely economic factors make it doubtful if these card-type tools can index in greater depth than they are already doing.
