This paper describes how two small non-profit libraries successfully computerized their periodical record and routing systems. The steps required in gaining acceptance of the idea, planning, designing, installing, and perfecting each system are included. The Population Council library, whose clerical staff was formerly responsible for manually routing periodicals to library staff, designed a program where the computer actually printed three types of routing slips, matching the existing system. Journals were routed in three ways: (1) to a particular staff member for a check of contents for possible abstracting for the Population Council's monthly publication; (2) contents' pages of journals to a large number of staff for check to see if any wanted to see the entire issue; and (3) the journal itself to all those interested in seeing every issue, regardless of content. The Rockefeller Foundation Library's system has the capability of producing on-demand lists of titles received, in alphabetical order, by subject, with holdings; lists of titles received arranged by the individual who saw them; and lists of titles needing renewal in the upcoming month.
