This document is the last of a series of eight reports of a project undertaken to (1) investigate the ways in which the National Agricultural Library (NAL) could utilize existing bibliographic data bases, (2) define the problems associated with efficient utulization of these data bases, and (3) develop approaches to solving these problems by intellectual or mechanical means. The report consists of three basic sections: (1) an introduction and brief summary; (2) a more detailed discussion of the seven technical tasks and the findings of each, and (3) a set of recommendations on how the work of this project may be applied to further research and development concerning data base utilization. The recommendations outline eight tasks that must be undertaken prior to the implementation of a full-scale system: (1) coordination of NAL machine formats, (2) data conversion, (3) subject vocabulary conversion, (4) data filtering, (5) file creation and maintenance, (6) index building, (7) retrieval and searching, and (8) investigation of communication and time-sharing requirements. An appendix contains a comparative survey of available computer software packages which could be used in an NAL data base system. (JW)
