Did you know there are different search interfaces for WorldCat, the world's largest library catalog?
WorldCat has long been a genealogy research staple, containing records for 1.5 billion items in library collections all over the world. In the last few years, OCLC, WorldCat's parent, opened the WC database to the general public. The advanced search interface for the public version is very clean and straightforward:
However, there's also an academic search interface for WorldCat that gives you the opportunity do more sophisticated searches:
To find the academic search version, Google the name of the nearest college or university library + WorldCat. Some libraries may have licenses with OCLC that limit access to students, faculty, and on-campus users, but others will allow public and remote access.
Both the public and the academic interfaces search the same database with 1.5 billion records. But if you're interested in a more powerful way to search 1.5 billion library records, try the academic version of WorldCat.
