Two overall levels of bibliographical control are desirable: one should be as complete as possible; the other should be a selection of prime items whose titles are organized for ease and effectiveness of consultation and decision making about the texts which are worth looking up; and this selection should be the aim of a complementary computer service. Recommendations of this study are: "Library Literature" should be continued and developed as the inclusive bibliographical control for the library and information field. Its style should change; entries should be more akin to those in the "Readers' Guide," very desirably in conjunction with research into the most effective style and type of entry for rapid scanning in long lists. Under any heading, entries should be arranged in inverse chronological order. Attention should be paid to semantics so headings will be used reasonably precisely, and to aid in this development semantic studies should be undertaken. In making "Library Literature" truly comprehensive, consideration should also be given to coverage for the earlier volumes of titles recently incorporated or still to be included. A complementary service should be planned. Undoubtedly this should be a computer record developed and maintained along cooperative lines. (see also LI 002 796 through LI 002 805 and LI 002 807).
