The Philatelic Digital Library Project was conceived to work closely to the Project Gutenberg Distributed Proofreaders and the Project Gutenberg to create, organize and preserve a philatelic literature collection.
Distributed Proofreaders provides a web-based method to ease the conversion of Public Domain books into e-books. By dividing the workload into individual pages, many volunteers can work on a book at the same time, which significantly speeds up the creation process.
