You will find the world's great literature here, especially older works for which copyright has expired. We digitized and diligently proofread them with the help of thousands of volunteers. 14 | 15 | No fee or registration is required, but if you find Project Gutenberg useful, we kindly ask you to donate a small amount so we can digitize more books, maintain our online presence, and improve Project Gutenberg programs and offerings. Other ways to help include digitizing more books, recording audio books, or reporting errors. 16 | 17 | News 18 | 19 | Project Gutenberg Supports Net Neutrality 20 | The Federal Communications Commission in the US is considering abandoning major components of network neutrality. This would legitimize "slow lanes" for network traffic that does not come from commercial partners of network providers. Sites where content is free, and generates no revenue - such as Project Gutenberg - would be at risk for downgraded speeds, access fees imposed by your network provider, or ads embedded by your network provider. Comments are solicited by the FCC at www.fcc.gov. Project Gutenberg encourages you to send messages to the FCC and your lawmakers, to express your views on this important issue. 21 | 22 | The Public Domain will grow again in 2019 23 | In the US, annual copyright term expiry is set to begin again in 2019, after a 20-year hiatus due to the Copyright Term Extension Act of 1998. On January 1, 2019, items published in 1923 will enter the public domain in the US. In the early days of Project Gutenberg, growth of the public domain on January 1 was an annual event. See Duke Law's "Public Domain Day"for a listing of many items that were scheduled to enter the public domain, but have yet to do so because of the 1998 extension. Some notable items scheduled to enter the public domain in 2019 include Felix Salten's "Bambi" and Kahlil Gibran's "The Prophet." 24 | 25 | Site Map 26 | 27 | Find eBooks 28 | Book Search. 29 | Recently added eBooks. 30 | Most Frequently Downloaded eBooks and Top 100 eBooks this month. 31 | Bookshelves of related eBooks. 32 | New Books Feeds. 33 | Browse Catalog: Browse and search, including full-text search. 34 | Offline Catalogs: handy book Listings to consult offline. 35 | Visit self.gutenberg.org, for free eBooks by contemporary authors. 36 | Help and Information 37 | Mobile Reader Devices How-To: Using Kindle, Nook, cell phone, and other mobile devices and readers. 38 | How-To and FAQs: In depth information about many topics. 39 | How to Help 40 | Report errors, bugs, typos (or, see detailed information about errata reporting) 41 | Volunteering. 42 | Distributed Proofreaders.
