Indeed, the curator of silver at the Smithsonian was enthusiastic over the possibilities of the system, providing her with a useful means of categorizing her ma- terials. In short, for certain types of collec- tions, this system may be one answer for the mechanical means of information re- trievaL-Marcus A. McCorison, American Antiquarian Society. Interlibrary Request and Loan Transac- tions Among Medical Libraries of the Greater New York Area. By Lee Ash and Vernon R. Bruette. New York: The Survey of Medical Library Resources of Greater New York, 1966. 199p. $5. (66- 26014). Interlibrary loans are big business. This survey provides badly needed facts and suggests trends. While some of the findings are hardly unexpected, there are a few surprises. The survey was set up in 1963 by funds from the Health Research Council of the City of New York. Gertrude Annan served as principal investigator with Jacqueline Felter and Erich Meyerhoff as co-investi- gators. The Medical Library Center of New York supplied office space and equipment. The original broad charge to the surveyors was soon narrowed to concentrate on inter- library loans. The surveyors pragmatically decided to use all of New York state and the area from Groton , Connecticut, through northern New Jersey for loans and requests. In addition, loans made to the survey libraries from the College of Physicians of Philadelphia and the National Library of Medicine were in- cluded. Questionnaires were sent to 441 libraries, 278 returned completed reports, and 224 agreed to take part in the survey. Of the 217 libraries which remained in the program for the full year, seventy-nine pro- vided the bulk of the material. The data used, which included requests for original materials and for photorepro- ductions, amounted to 99,452 transactions (27,825 requests by the survey libraries, and 71 ,627 requests to the survey libraries). Of the serial requests made by the survey libraries 42.1 per cent were made by nine- teen commercial concerns. The requests re- ceived by the survey libraries showed that 50.1 per cent came from the commercial concerns (mostly pharmaceutical houses ) . The National Library of Medicine received 14.5 per cent of all serial requests by the survey libraries. Some 9.6 per cent of the total requests went unfilled. One of the biggest surprises for the sur- veyors was that almost 18 per cent of the requests by the survey libraries were made outside the survey area. This has some im- portant implications for regional planning. Tables break down the transactions by borrower, lender, and type, date, language, and subject of publication. The source records have been kept at the Center and are available for further study. The sur- veyors hope to publish elsewhere more de- tailed tables showing rank orders and num- bers of requests and loans for the frequent- ly-used journals. In addition to drawing attention to the need for detailed cost studies (to include both direct and indirect elements), the sur- veyors conclude by emphasizing that the burden on the larger libraries must be re- lieved, that these libraries should "supple- ment" not "supply." They also stress the importance of on-the-spot service in the small libraries. This is a census of a region and not a sample that could validly be extended over the country. It is a valuable report that should have a profound effect in the New York region and could have an effect nation- ally if other groups pick up the challenge and make comparable studies.-William K.

This tastefully de- signed volume was published as a token of respect for Gjelsness' long, distinguished, and fruitful career as librarian, library edu- cator, and scholar.
