Through existing services and programs, it is now economically feasible to store, preserve, and publish virtually every written and spoken word. The critical task is that of selectivity, both in storage-preservation and in dissemination. Selective dissemination is currently implemented by University Microfilms through (1) hard-copy production of journal articles abstracted but not published elsewhere; (2) post-publication production of reprints or copies of journal articles; and (3) small-run publishing of highly specialized books.
