#### Google API client libraries

We also offer generic Google API client libraries that you can use with Books API.

The Google API client libraries, which are available in a number of popular programming languages, make it easy to use the Books API.

In the following tables, the first column shows each library's stage of development (note that
some are in early stages), and links to documentation for the library. The second column links to
available samples for each library.
