Earlier this year, the Internet Archive gathered a small group of people in San Francisco to discuss whether this was possible. Could we build something so grand? We concluded that we could. We located a copy of the Library of Congress card catalog, phoned publishers and asked them for their data, created a brand new database infrastructure for handling millions of dynamic records, wrote a new type of wiki that lets users enter structured data, set up a search engine to look through it all, and made the resulting site look good.
We hooked it up to the Internet Archive's book scanning project, so that you can read the full text of all the out-of-copyright books they've made available. And we hope to add a print-on-demand feature, so that you can get nice paper copies of these scanned books, as well as a scan-on-demand feature, so you can fund the scanning of that out-of-copyright book you've always loved.
But we can only do so much on our own. Hopefully we've done enough to make it clear that this project is for real—not simply another pie-in-the-sky idea—but we need your help to make it a reality. So we're opening up the demo we've built so far, opening up the source code, opening up the mailing lists, and hoping you'll join us in building Open Library. It sure is going to be a fun ride.

Zebra is a high-performance, general-purpose structured text indexing and retrieval engine. It reads structured records in a variety of input formats (eg. email, XML, MARC) and allows access to them through exact boolean search expressions and relevance-ranked free-text queries.
Zebra supports large databases (more than ten gigabytes of data, tens of millions of records). It supports incremental, safe database updates on live systems. You can access data stored in Zebra using a variety of Index Data tools (eg. YAZ and PHP/YAZ) as well as commercial and freeware Z39.50 clients and toolkits.
Zebra is free software, available under the GPL license. It may be used by anyone without charge. If you wish to incorporate Zebra into a commercial software distribution, please contact us about alternative licenses.
