From Current Cites:
Coyle, Karen. “Mass Digitization of Books” The Journal of Academic Librarianship 32(6)(November 2006): 641-645. – A very well done overview of mass and near-mass digitization of books by Google, the Open Content Alliance, Microsoft, Project Gutenberg, and many library-based projects. Coyle touches on issues such as workflow, output and book structure, user interface, standards, preservation, and scoping the project. If you’re interested in this topic, this is the single best overview currently available. Highly recommended.
