College and Research Libraries 548 I College & Research Libraries • November 1977 Ladd, Boyd. National Inventory of Libra- ry Needs, 1975. Resources Needed for Public and Academic Libraries and Pub- lic School Library/Media Centers. A Study Submitted by Boyd Ladd to the N a- tiona! Commission on Libraries and Infor- mation Science, March 1977. Washing- ton: Govt. Print. Off., 1977. 275p. $3.60. LC 77-8216. What an infuriating grab bag of a vol- ume this is! If only it had been called "A Source Book of Resource Data Collected by LIBGIS" or some such title rather than National Inventory of Library Needs; the one title so modest, the other so certain, so sure. The book . is a compilation of public li- braries', school library I media centers', and academic libraries' data reported in the 1974 and 1975 LIBGIS surveys to the Na- tional Center for Education Statistics. The data are then compared with standards "to the degree that professional deliberation has provided some consensus on the levels 'needed.'" Then projections of ·"need" are made. To concentrate on academic libraries: Did you know that a one-time expenditure of $1.5 billion would buy us all the books we are missing and that we would only also have to increase our annual expenditure by about a third, from $300 million to $400 million a year, and we could keep steady? Yet did you also know that, in total, collec- tions in academic libraries are 99 percent "adequate" but that two-year colleges are 50 percent "adequate" and public four-year col- leges are exactly 100 percent "adequate"; that private universities are 177 percent "adequate," while public universities are only 111 percent adequate? What a mistake to qualify an absolute term like "adequate," and what nonsense the results! What I've tried to illustrate in the above examples is the wisdom of a comment made by Boyd Ladd, the compiler, in his preface: "Interpretive analysis has intentionally been limited, in the expectation that many analy- ses will and should be made from different philosophic stances." Now, therefore, my philosophic stance> again concentrating on academic libraries: 1. The data, inasmuch as we have learned to count things consistently, are fine. Mr. Ladd's compilations and tables are excellent, diligent, and comprehensive. 2. The data are not strong enough to withstand the analysis thrust upon them, and the misinterpretations that are bound to follow when budget offi- cers get their hands on them. 3. The standards are wrong and, in some cases, have been specifically discredit- ed. Current knowledge and the re- sults of work, such as the Pittsburgh work on collection use, the "inventory law," and so on, have not yet been in- corporated into "official" standards. 4. The standards and the data must be improved before such analyses can be made. 5. The standards are. all input standards. What ·is needed is a performance stan- dard, the technique for the attainment . of which will vary from library to li- brary. That is, some will need to in- vest in collections, others in interli- brary loan, others in on-line retrieval, others in student instruction, and so on. 6. I propose the following performance standard: 90 percent of all requests made of the library satisfied within forty-eight hours. In fairness, I have to say that both Al Trezza in his foreword and Ladd in his preface recognize the shortcomings and weaknesses. They rightly see the work as being stimulative of further work, particu- larly in the essential field of user studies. As Trezza says in his foreword: The extensive data will no doubt sug- gest some relationships and interpretations not expected, and lead to some hypotheses which challenge the conventional wisdom in our profession. Resulting questions are expected to stimulate further analysis lead- ing to a better understanding of the re- sources appropriate to effective library and information services. This compilation is probably the most important book of the year. We should all buy it, read it, understand it; and then sit down and have a good long think.-Glyn T.
