Peer reviewedWestland, J. Christopher – Journal of the American Society for Information Science, 1991
Discusses the cost of constructing a hypertext database and suggests cost forecasting approaches that can be used to determine whether organizations can internally fund a hypertext database, or whether producers can afford to market hypertext databases. Production costs in differing hypertext strategies are also compared. (27 references) (LRW)
