For example, if you distribute copies of the 
library, whether gratis or for a fee, you must 
give the recipients all the rights that we gave 
you. You must make sure that they, too, receive 
or can get the source code. If you link a 
program with the library, you must provide 
complete object files to the recipients so that 
they can relink them with the library, after 
making changes to the library and recompiling 
it. And you must show them these terms so 
they know their rights.

Our method of protecting your rights has two 
steps: (1) copyright the library, and (2) offer 
you this license which gives you legal 
permission to copy, distribute and/or modify 
the library.

Also, for each distributor's protection, we want 
to make certain that everyone understands that 
there is no warranty for this free library. If the 
library is modified by someone else and passed 
on, we want its recipients to know that what 
they have is not the original version, so that 
any problems introduced by others will not 
reflect on the original authors' reputations.

Finally, any free program is threatened 
constantly by software patents. We wish to 
avoid the danger that companies distributing 
free software will individually obtain patent 
licenses, thus in effect transforming the 
program into proprietary software. To prevent 
this, we have made it clear that any patent must 
be licensed for everyone's free use or not 
licensed at all.

Most GNU software, including some libraries, 
is covered by the ordinary GNU General 
Public License, which was designed for utility 
programs. This license, the GNU Library 
General Public License, applies to certain 
designated libraries. This license is quite 
different from the ordinary one; be sure to read 
it in full, and don't assume that anything in it is 
the same as in the ordinary license.

The reason we have a separate public license 
for some libraries is that they blur the 
distinction we usually make between 
modifying or adding to a program and simply 

using it. Linking a program with a library, 
without changing the library, is in some sense 
simply using the library, and is analogous to 
running a utility program or application 
program. However, in a textual and legal 
sense, the linked executable is a combined 
work, a derivative of the original library, and 
the ordinary General Public License treats it as 
such.

Because of this blurred distinction, using the 
ordinary General Public License for libraries 
did not effectively promote software sharing, 
because most developers did not use the 
libraries. We concluded that weaker conditions 
might promote sharing better.

However, unrestricted linking of non-free 
programs would deprive the users of those 
programs of all benefit from the free status of 
the libraries themselves. This Library General 
Public License is intended to permit 
developers of non-free programs to use free 
libraries, while preserving your freedom as a 
user of such programs to change the free 
libraries that are incorporated in them. (We 
have not seen how to achieve this as regards 
changes in header files, but we have achieved 
it as regards changes in the actual functions of 
the Library.) The hope is that this will lead to 
faster development of free libraries.

The precise terms and conditions for copying, 
distribution and modification follow. Pay close 
attention to the difference between a "work 
based on the library" and a "work that uses the 
library". The former contains code derived 
from the library, while the latter only works 
together with the library.

Note that it is possible for a library to be 
covered by the ordinary General Public 
License rather than by this special one.
