Although especially written for the FreeBSD project, this license shows you how to draft a very simple non-copyleft license for documentation works.

Invariant sections
Invariant sections are a special provision of the GFDL which, if used, prevent anyone from modifying the parts of the work which are defined as "invariant". The Free Software Foundation finds it useful to protect some special "non-functional" parts of the work, like a statement of intent (the motivation for invariant sections was, allegedly, to prevent the GNU Manifesto to be removed or modified in GNU documentations).
We believe, however, that freedom should apply to all kind of works, and that what is "functional" in one situation can be "artistic" in another - and vice-versa. Consequently, a work using invariant sections to forbid some kinds of modifications to the work cannot be considered completely free.
Unless additional permissions are granted, all FDL works contain unmodifiable sections which aren't called Invariant Sections, such as a copy of the license embedded in the document itself.
GNU General Public License
- Aliases: GNU GPL, GPL
- Current version: 3.0
- Author: Free Software Foundation
- License text (English)
The GNU GPL is, according to various statistics, probably the most used free software license. It was also the first license to implement the concept of copyleft, guaranteeing that "GPL'ed" free software cannot become, or take part in, non-free software.
Although the GPL is primarily intended for software programs, it is worded so as to apply to many different kinds of works. The main condition for the GPL to be applicable to a type of work is that it admits the notion of a preferred form of a work for making modifications to it (be it source code in a computer language, music score notation, digital graphics under a format retaining structure, etc.). For example, there are many occurrences of text or graphics released under the GPL.
Lizenz für Freie Inhalte
- Aliases: LFFI
- License Text (German)
AFAIK only used by the german portal neppstar for free music and video. Anyway, it seems to be a valid free license.

MIT License

This license is arguably the simplest form of the BSD-like licenses for software. All the license, except for the no-warranty statement, is condensed in two short paragraphs.
There are variants, like the current BSD license which has an additional provision forbidding endorsement of derived works using the name of the original authors.
