Cooperative exchange of digital documents among electronic libraries. The case of Latin America: Model and cost analysis.


This study examines if document density, defined as the number of documents available in given subject categories, in sub-sets of documents in research libraries, can be used to rank document sub-sets in the order in which they should be digitized. Document density related data for document sub-sets are compared to past use data to determine if the former can be used as a surrogate for the latter. The study also assesses the economic viability of developing trans-national cooperative agreements to exchange digitized documents by analyzing and comparing reformatting and access costs.
