October 2003 > The collection doubled in 18 months From April 2002 to October 2003, in 18 months, the collection of ebooks doubled, going from eBook #5000 to eBook #10000, with an average of 348 new ebooks per month in 2003. The fast growth was the hard work of Distributed Proofreaders, now going at full speed to digitize books and share the proofreading of ebooks between many volunteers. December 2003 > The first Project Gutenberg DVD eBooks were also copied on CDs and DVDs. As blank CDs and DVDs cost next to nothing, Project Gutenberg began burning and sending a free CD or DVD to anyone asking for it. People were encouraged to make copies for a friend, a library or a school. Released in August 2003, the Best of Gutenberg CD contained 600 ebooks. The first Project Gutenberg DVD was released in December 2003, with the burning of most titles (9,400 ebooks). 2003 > The Project Gutenberg Consortia Center (PGCC) The Project Gutenberg Consortia Center (PGCC) was affiliated with Project Gutenberg in 2003. Since 1997, PGCC had been gathering collections of existing ebooks, as a complement to Project Gutenberg working on producing ebooks. As explained by Michael Hart in January 2009: "The Project Gutenberg Consortia Center has over 75,000 ebooks rendered as PDF files (...). The difference? These files were prepared by other eLibraries, not Project Gutenberg, and are using our worldwide distribution network to be seen."
