2004. Project Gutenberg Europe celebrated its first 100 books in June 2005.
These books were in several languages, a reflection of European linguistic
diversity, with 100 languages planned for the long term.

In January 2005, Project Gutenberg reached the landmark of 15,000 books. eBook
number 15000 is The Life of Reason, by George Santayana (published in 1906). In
July 2005, Project Gutenberg of Australia (launched in 2001) reached the
landmark of 500 books. New teams were getting ready to launch Project Gutenberg
Canada, Project Gutenberg Portugal and Project Gutenberg Philippines over the
next years.

What about languages? If there where were works in 25 languages only in February
2004, there were works in 42 languages in July 2005, including Iroquoian,
Sanskrit and the Mayan languages. On July 27, 2005, out of a total of 16,800
books, the seven "main" languages were: English (with 14,548 books), French (577
books), German (349 books), Finnish (218 books), Dutch (130 books), Spanish (103
books) and Chinese (69 books). There were books in 50 languages in December
2006. On December 16, 2006, out of a total of 19,996 books, the main languages
were English (17,377 books), 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).

In December 2006, Project Gutenberg reached the landmark of 20,000 books. eBook
number 20000 was the audio book of Twenty Thousand Leagues Under the Sea (Vingt
mille lieues sous les mers), by Jules Verne (published in 1869). Half of these
20,000 books were produced by Distributed Proofreaders since October 2000, with
a monthly average of 346 new digitized books in 2006. If 32 years were necessary
to digitize the first 10,000 books, between July 1971 and October 2003, 3 years
and 2 months were necessary to digitize the following 10,000 books, between
October 2003 and December 2006. Project Gutenberg of Australia was about to
reach 1,500 books (this goal was achieved in April 2007) and Project Gutenberg
Europe reached 500 books.

The section Project Gutenberg PrePrints was set up in January 2006 to collect
items submitted to Project Gutenberg which for some reason were interesting
enough to be available online, but not quite ready yet to be added to the main
Project Gutenberg collection, the reason being for example missing data,
low-quality files, formats which w
