What is an OPAC?
An OPAC is an automated catalog of online public access library materials. Generally, both the library staff and the public have access to it in several terminals within the library or from home via the Internet.
The OPAC is often part of an integrated library system.
It is not exactly a information resource, but you can get from an OPAC information about articles of your interest. For example, you can get in which lbraries it is aviable to read it, or you can get some extra information interesant for you like year of publication.
An example of OPAC: WorldCat.
At present, some 30,000 libraries have bibliographic records from OCLC's OPAC, called WorldCat, a catalog of library materials with the collaboration of public and private libraries throughout the world, especially in the U.S.A. and Canada.
WorldCat shows how many libraries have the same book or material. WorldCat users must connect their own library OPAC to see information from other libraries. The OCLC WorldCat is not technically an OPAC in itself, it is better called as Macro OPAC, is a bibliographic database used primarily by library staff (librarians) of the institutions that have an annual subscription to OCLC services. It is not used by users or the general public unless your local library subscribes to serve the OCLC FirstSearch reference.
How can you find it?
You can find WorldCat from the institutions that have an annual supscription to OCLC services.
It is also searchable by search engines like Google and Yahoo, searching for "OCLC WorldCat Open".
