Title: A life-cycle cost analysis for the creation, storage and dissemination of a digitized document collection

Abstract: Traditional paper-based document collections in libraries have been affected by substantial costs related to increasing publication output coupled with decreasing levels of funding for the maintenance of these collections. Many libraries, in response to this problem, have initiated projects to electronically scan and store portions of their paper-based document collections as digitized documents, available for retrieval through computer networks. While cost studies accompanying some of these projects indicate a significant cost advantage for a digitized document format over a paper-based document format, these projects are limited to collections of a single library or group of libraries and indicate little cost information which can be used to decide whether to digitize paper-based documents on a national scale. Employing life cycle cost analysis, this study illustrated that for given document selection criteria, the net present value cost of digitizing the estimated national collection of monographic documents was far less than the net present value cost of maintaining the same documents in a paper-based format.

Using a sample of document records and their corresponding library locations drawn from national bibliographic databases, estimates were made for the size and physical characteristics of the monographic document population in U. S. academic and public libraries, as well as the population proportion of unique documents to duplicate documents in the collections of these libraries. Two document selection criteria were used to divide the sample of unique documents into ranked document sets: the speed of document processing (which included values relating to the physical size, the number of pages and the presence or absence of illustrations for each document) and the projected future demand for documents (which included values relating to the number of locations, the age and the language of publication for each document). Estimates were made of the size of each document set relative to the estimated document population, the corresponding proportion of unique documents to duplicate documents for each document set relative to the estimated document population and the distribution of projected future demand for each document set relative to the estimated projected future demand for documents within the estimated document population. Relevant cost variables were used to model the life-cycle costs for both the selection, production, storage and accession of the estimated document population as digitized documents and the storage and accession of the estimated document population as paper-based documents. Total net present value cost throughout the assumed life-cycle of the model was used for comparing the cost of various percentile combinations of document sets in digitized format and paper-based format with the cost of maintaining all document sets in paper-based format.

This comparison produced steadily decreasing net present value cost totals for various percentile combinations of digitized document sets and paper-based document sets as greater numbers of paper-based document sets were digitized. Sensitivity analysis of the model, using increasing values for major model variables, produced no significant change in this result, indicating that very large net present value cost savings can be attained if a digitization project on a national scale is undertaken by academic and public libraries.
