The Linux Documentation Project (TLDP) began as a way for Linux hackers to share their documentation with each other and with their users, and for users to share documentation with each other.

The LDP originally began as an FTP site in 1992, but it went on the World Wide Web at MetaLab in 1993. It is believed to have been the first Linux related website ever.

Today, the LDP serves over 475 documents contributed by even more authors. About a dozen of them are book length, and most of those are available in print from major technical publishers including O'Reilly. The LDP publishes many HowTo documents, which instruct a user on the specific steps to take to achieve a desired goal. These goals are sometimes very specific, such as configuring a particular modem, and sometimes very broad, such as how to administer a network for an ISP.

Very broad topics are covered in the guides, which are book-length documents, usually on broad subjects such as security or networking.

The LDP also publishes Frequently Asked Question (FAQ) lists, man pages and other documents, as well as two webzines, the Linux Gazette and Linux Focus.

Much of the LDP collection is licensed under the GNU Free Documentation License. Many other licenses are also used, as long as they are freely distributable. Current policy recommends the GFDL or the Open Publication License without exercising options A or B.

Linux Network Administrators' Guide is one book in the series.
