id="id00033">"Light Literature" was the main section in number of ebooks. As explained on the website in 1998, "The Light Literature Collection is designed to get persons to the computer in the first place, whether the person may be a pre-schooler or a great-grandparent. We love it when we hear about kids or grandparents taking each other to an etext of 'Peter Pan' when they come back from watching Hook at the movies, or when they read 'Alice in Wonderland' after seeing it on TV. We have also been told that nearly every Star Trek movie has quoted current Project Gutenberg etext releases (from 'Moby Dick' in 'The Wrath of Khan'; a Peter Pan quote finishing up the most recent, etc.) not to mention a reference to 'Through the Looking-Glass' in JFK. This was a primary concern when we chose the books for our libraries. We want people to be able to look up quotations they heard in conversation, movies, music, other books, easily with a library containing all these quotations in an easy-to-find etext format."

Project Gutenberg has selected books intended for the general public. It has not focused on providing authoritative editions. "We do not write for the reader who cares whether a certain phrase in Shakespeare has a ':' or a ';' between its clauses. We put our sights on a goal to release etexts that are 99.9% accurate in the eyes of the general reader. Given the preferences our proofreaders have, and the general lack of reading ability the public is currently reported to have, we probably exceed those requirements by a significant amount. However, for the person who wants an 'authoritative edition' we will have to wait some time until this becomes more feasible. We do, however, intend to release many editions of Shakespeare and the other classics for comparative study on a scholarly level."

In August 1998, Michael Hart wrote in an email interview: "My own personal goal is to put 10,000 etexts on the net [this goal was reached in October 2003] and if I can get some major support, I would like to expand that to 1,000,000 and to also expand our potential audience for the average etext from 1.x% of the world population to over 10%, thus changing our goal from giving away 1,000,000,000,000 etexts to 1,000 times as many, a trillion and a quadrillion in U.S. terminology."

# 1,000 to 10,000 ebooks

From 1998 to 2000, the "output" was an average of 36 books per month.

Project Gutenberg reached 2,000 ebooks in May 1999. eBook #2000 was "Don Quijote" (1605), by Cervantes, in Spanish, its original language.

Project Gutenberg reached 3,000 ebooks in December 2000. eBook #3000 was "A l'ombre des jeunes filles en fleurs" (In the Shadow of Young Girls in Flower), vol. 3 (1919), by Marcel Proust, in French, its original language.

Project Gutenberg reached 4,000 ebooks in October 2001. eBook #4000 was "The French Immortals Series" (1905), in English. This book is an anthology of short fictions by authors from the French Academy (Académie française): Emile Souvestre, Pierre Loti, Hector Malot, Charles de Bernard, Alphonse Daudet, and others.

Project Gutenberg reached 5,000 ebooks in April 2002. eBook #5000 was "The Notebooks of Leonardo da Vinci" (early 16th century). Since its release, this ebook has stayed in the Top 100 of downloaded books.

In 1988, Michael Hart chose to type in "Alice's Adventures in Wonderland" and "Peter Pan" because they would each fit on one 360 K disk, the standard of the time. In 2002, the standard disk was 1.44 M and could be compressed as a ZIP file.

A practical file size is about 3 million characters, more than long enough for the average book. The ASCII version of a 300-page novel is 1 M. A bulky book can fit in two ASCII files, that can be downloaded as is or in ZIP format. An average of 50 hours is necessary to get an ebook selected, copyright-cleared, scanned, proofread, formatted and assembled.

A few numbers are reserved for "special" books. For example, eBook #1984 is reserved for George Orwell's classic, published in 1949, and still a long way from falling into public domain.

The "output" in 2001 and 2002 was an average of 100 books per month.

In spring 2002, Project Gutenberg's ebooks represented 25% of all the public domain works freely available on the web, an impressive result if we think of all the pages that were scanned and proofread by thousands of volunteers in several countries.

1,000 ebooks in August 1997, 2,000 ebooks in May 1999, 3,000 ebooks in December 2000, 4,000 ebooks in October 2001, 5,000 ebooks in April 2002, 10,000 ebooks in October 2003. eBook #10000 was The Magna Carta, signed in 1215 and known as the first English constitutional text.

From April 2002 to October 2003, in 18 months, the collections doubled, going from 5,000 ebooks to 10,000 ebooks, with a monthly average of 300 new ebooks. The fast growth was the work of Distributed Proofreaders, a website launched in October 2000 by Charles Franks to share the proofreading of books between many volunteers. Volunteers choose one of the books available on the site and proofread a given page. It is recommended they do a page per day if possible.

Books 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 to celebrate the first 10,000 ebooks, with the burning of most titles (9,400 ebooks).

# 10,000 to 20,000 ebooks

In December 2003, there were 11,000 ebooks, which represented 110 G, in several formats (ASCII, HTML, PDF and others, as is or zipped). In May 2004, there were 12,600 ebooks, with represented 135 G. With more than 300 new books added per month (338 books per month in 2004), the number of gigabytes was expected to double every year.

The Project Gutenberg Consortia Center (PGCC) was affiliated with Project Gutenberg in 2003, and became an official Project Gutenberg site. Since 1997, PGCC had been working on gathering collections of existing ebooks, as a complement to Project Gutenberg focusing on the production of ebooks.

In January 2005, Project Gutenberg had 15,000 ebooks. eBook #15000 was "The Life of Reason" (1906), by George Santayana.

What about languages? There were ebooks in 25 languages in February 2004, and in 42 languages in July 2005, including Sanskrit and the Mayan languages. The seven top languages—with more than 50 books—were English (with 14,548 ebooks on July 27, 2005), French (577 ebooks), German (349 ebooks), Finnish (218 ebooks), Dutch (130 ebooks), Spanish (103 ebooks), and Chinese (69 ebooks). There were ebooks in 50 languages in December 2006. The ten top languages were English (with 17,377 books on December 16, 2006), French (966 books), German (412 books), Finnish (344 books), Dutch (244 books), Spanish (140 books), Italian (102 books), Chinese (69 books), Portuguese (68 books), and Tagalog (51 books).

Project Gutenberg was also spreading worldwide.

In July 2005, Project Gutenberg Australia (launched in 2001) had 500 ebooks.

In Europe, Project Rastko, based in Belgrade, Serbia, launched Distributed Proofreaders Europe (DP Europe) in December 2003 and Project Gutenberg Europe (PG Europe) in January 2004. Project Gutenberg Europe released its first 100 ebooks in June 2005. These books were in several languages, as a reflection of European linguistic diversity, with 100 languages planned for the long term.
