Problems associated with the impact of publications of the federal government on libraries are categorized in two ways. The first relates to the handling and organization of documents within libraries. No one approach is completely satisfactory; in practice, larger libraries tend to process and house documents separately from other publications, a method which may well restrict the flow of information to users. The second group of problems is associated with the growing tendency to exclude government-produced information from the depository library system, which itself may be inadequate to serve an expanding population and educational system.
Citation and subject index search results were analyzed with relative recall ratio, relative rejection ratio, noise ratio, redundancy ratio, unit search decision, and unit search time as evaluative measures. Subject indexing was found to have greater efficacy than citation indexing. There is a very highly significant difference between the proportions of pertinent references among the unique references retrieved by the two types of searches. A backward search without noise elimination retrieved numerous references, mostly noise. The data indicate that it would be useless to do machine searches to retrieve all references with two-linked or three-linked connections, etc.
A substantial change is suggested in a key library activity-the shelving and storing of books, and optionally, in circulation-through the use of an individual box for each book. For thousands of years libraries have been forced to shelve books either in relative or fixed location. An integration or combination of fixed and relative location opens an entirely new range of possibilities affecting a substantial proportion of all library operating procedures. Few have imagined these potentialities in the past because the simple, but profoundly crucial base has not been possible with existing technology.
The Margaret Mann Citation in Cataloging and Classification is awarded in 1968 to Paul S. Dunkin in recognition of his contribution to the development of the philosophy and techniques of organizing recorded human knowledge. An innovative practitioner, stimulating teacher, chronicler and critic, author and editor, indefatigable committeeman and elder statesman with a refreshingly young perspective, Dr. Dunkin has earned the respect of the entire library profession for his modestly-worn erudition, grace and wit.
