DO NOT USE! LICENSING / LEGAL ADVICE IS OFF TOPIC -- LGPL questions should be asked on opensource.stackexchange.com - The GNU Lesser General Public License is a weak copyleft free software license and is the second most popular open source license. It is generally designed for and used by software libraries.

NOTE - Licensing is no longer a valid topic for Stack Overflow. If you have licensing questions, please ask them on OpenSource.SE (which has its own LGPL tag). Legal questions may be asked on Law.SE

The [GNU Lesser General Public License][1] (formerly the GNU Library General Public License) or LGPL is a free software license published by the Free Software Foundation (FSF). It was designed as a compromise between the strong-copyleft GNU General Public License or GPL and permissive licenses such as the BSD licenses and the MIT License.

The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications, most notably Mozilla and OpenOffice.org and sometimes media as well.
