Libraries should resist the temptation to relinquish to computing centers the burden of looking after the university's digital data record resources for a growing volume of intellectually important material will arrive at the university on digital data tapes. If the user must arrange for access to this material outside the library, he will be seriously disadvantaged. When a library assumes responsibility for digital data record resources, the selection of access techniques becomes the central question. The use of interactive techniques in which the user is in direct communication with the data file, combined with full-text displays is described. The model Library Program, discussed in Section III, deals with procedures that assist the user who seeks information in a mixed regime of machine access techniques and conventional library operations. The program's objective is to examine system configurations from the viewpoint of cost-benefits relationships and to study interrelationships among factors such as data-base size, content and cost, user population, equipment utilization, hardware considerations, and networking through use of electrical communications.
