Selective Dissemination of Surrogates
Library material at hand is used much more extensively than that at a distance--say, in a library. This is so because it was selected for relevance to one's interests and because it is handier. From this observation, one should be able to increase the use of library materials by arranging to have them at hand. The abstract journal, for example, benefits subscribers by handy issues. Subscription to an abstract journal is a form of broadly selective dissemination. More selective dissemination of abstracts would be even more efficient. Probably more than 99 percent of the abstracts in a large abstract journal are of no interest to the average subscriber. For primary journals, only a few percent of the articles published in a year may be of interest to the subscriber. Wastes such as these can be reduced by the selective dissemination of references (SDR) and of surrogates (SDS). Cost and price seem to be the only deterrents to the selective dissemination of abstracts (SDA). By way of contrast, the value of a service promotes its adoption. Subject, author, and other index entries for abstracts have been matched against the profiles of abstract users and only those abstracts sent to users that match the profiles. This avoids sending users the 90 percent or more of irrelevant material. This has been done extensively in organizations. For example, in aerospace libraries, NASA and AIAA abstracts have been selectively disseminated to engineers by running computer
