TrueType font families: Liberation Sans, Liberation Serif and Liberation Mono. These fonts are metric-compatible withMonotype Corporation 'sArial ,Times New Roman , andCourier New respectively. Liberation Sans, Liberation Serif were derived from Ascender Sans, Ascender Serif respectively; Liberation Mono"' uses base designs from Ascender Sans and Ascender Uni Duo.They are available under the
GNU General Public License with a font embedding exception, which states that documents embedding these fonts do not automatically fall under the GNU GPL.History
The fonts were developed by
Steve Matteson of Ascender Corp. as Ascender Sans and Ascender Serif. A variant of this font family, with the addition of a monospaced font and open-source license, was licensed byRed Hat , Inc. as the Liberation font family.

The first release was a set of fully usable fonts, but they lacked the full hinting capability. The second release, made available in the beginning of 2008, provides full hinting of the fonts.
The Fedora Project, as of version 9, features slightly revised versions of the Liberation fonts contributed by Ascender. These include a slashed zero and various changes made for the benefit of
internationalization . [https://bugzilla.redhat.com/buglist.cgi?product=Fedora&version=rawhide&component=liberation-fonts Bugzilla entries for the revised Liberation fonts included in Fedora 9]Characteristics

License controversy
This license for the Liberation fonts adds several clauses to the base GPL. The debian-legal mailing list, a list for discussing legal issues in
Debian software, has discussed the impact of a clause requiring physical products including the fonts to make it possible for users to access, modify, and reinstall the fonts on the product. Concerns about this clause making the fonts non-redistributable or perhaps violating the copyright ofFree Software Foundation on the GPL were raised. [cite web
