If you haven’t visited The Open Library, PG says you should become acquainted with this fabulous trove of old and less-old books.
From The Open Library:
One web page for every book ever published. It’s a lofty but achievable goal.
To build Open Library, we need hundreds of millions of book records, a wiki interface, and lots of people who are willing to contribute their time and effort to building the site.
To date, we have gathered over 20 million records from a variety of large catalogs as well as single contributions, with more on the way.
Open Library is an open project: the software is open, the data are open, the documentation is open, and we welcome your contribution. Whether you fix a typo, add a book, or write a widget–it’s all welcome. We have a small team of fantastic programmers who have accomplished a lot, but we can’t do it alone!
