Edited version of a paper presented at the conference: 'Information for the nation: appropriate technologies for information transfer' of the South African Institute for Library and Information Science in September 1992. For many South African librarians, appropriate technology means affordable technology. Part of the library community in the country has been preoccupied with expensive state-of-the-art information technology. Small information centres can use electronic bulletin boards to participate in local bulletin board networks linking a wide range of libraries and information centres in specific areas. Possible applications of such a system are outlined.
