The experience with various computer implementations at Lawrence Livermore Laboratory is described and it is concluded that resource-shared facilities, such as ADP service centers and general-purpose time-sharing systems, are adequate for off-line, batch-mode library housekeeping and for current awareness services, but are not well suited to…

Describes two factors affecting the results of manual and online information retrieval: the manner by which classification codes and key words are chosen, and the degree to which papers with comparable contents are accorded similar keywords. Of 14 alternative search strategies selected, the best consisted of using classification codes coupled with…

Describes a systematic approach to the design of fixed-length, derived, truncated search keys for corporate author records; and a statistical method for predicting the performance of search keys for files of arbitrary size. (VT)

Physical, economic, technical, and social constraints are analyzed in the case of the online vendor, and each component in the chain is considered separately. The user's problems are analyzed from the viewpoint of both the intermediary and the end user, and the effect of the changeover to a new system is considered. (Author)

An example of an on-line printout from the Dow Jones News/Retrieval Service (DJNR) is given accompanied by a brief discussion of how to use the service, description of how one library uses it, and some of its constraints. (JPF)
