This article examines the needs of users of taxonomic literature, specifically in relation to the transformation of traditional library material to digital form. It details the issues that arise in determining scanning priorities, avoiding duplication of scanning across the founding 12 natural history and botanical garden library collections, and the problems related to the complexity of serials, monographs, and series. Highlighted are the tools, procedures, and methodology for addressing the details of a mass-scanning operation. Specifically, keeping a steady flow of material, creation of page level metadata, and building services on top of data and metadata that meet the needs of the targeted communities. The replication of the BHL model across a number of related projects in China, Brazil, and Australia are documented as evidence of the success of the BHL mass-scanning project plan
