The introduction of a computerized biomedical network in three medical libraries in the State University of New York demanded a study of the various bibliographic records held by the libraries. The investigation produced figures relating to the total number of monographs held by each library and the number of unique titles owned by the network as a whole. These were broken down to identify the amount of works dating from 1962 or later, and estimates were made of the mean length of the normal bibliographic record, as well as of its traditional subareas. Thought was given to the implication of applying depth-indexing to monographs with reference to the length of the record.
纽约州立大学的三个医学图书馆引入计算机化生物医学网络，这就需要对图书馆所拥有的各种书目记录进行研究。调查得出了各图书馆所藏专著的总数以及整个网络所拥有的独特书名数量。这些数据被进一步细分，以确定1962年及以后出版的著作数量，并估算了正常书目记录的平均长度及其传统子领域。还考虑了根据记录长度对专著应用深度索引的影响。
