I heard a rumor last month that OCLC Worldcat was being released to the masses sometime in August. Okay, so it was more than rumor; InfoToday's Newsbreak ran a story by Paula Hane on the topic on July 17th. But I figured, why tell you about it until it's actually available! Well, now it is, according to Librarian In Black, who has a couple of good comments on the implementation.
This isn't the small subset of Worldcat data included in Yahoo and Google searches. According to Paula, "The WorldCat.org search box will make visible all 70-plus million records in the WorldCat database—not just the smaller data subsets of 3.4 to 4.4 million currently made available by the Open WorldCat partner sites, such as Google, Yahoo!, and others."
For those of my readers who aren't familiar with OCLC Worldcat, it's a collection of library cataloging records that tells you which books or periodicals are available, and the libraries where you can find them. The number of participating libraries is monumental. There's a good chance that your local public library is included, as well as academic libraries in your area. So if you're looking for a particular book, searching Worldcat should tell you the closest library that owns it. (Private firm libraries, as well as other special libraries have probably opted out of Worldcat.org since their collections aren't open to the public.)
You can even include the Worldcat search box on your web site, if you like:
I think it's very neat how they can deep link directly into a libraries catalog. (This isn't available for all libraries.) In other words, when I searched on "Clicker Training", I can see that the Pasadena Public Library has a book with those words in the title. When I click through, I go directly to the Pasadena Public Library catalog record. I'm just loving this.
I also like the "faceted browse" panel that allows users to refine their results by categories including author, subject, format, language and year of publication. Faceted searching/browsing is becoming increasingly popular as an easy way to help users narrow their search results. Considering that most users tend to search quite broadly by just typing a couple of words into a search box, whether it's Google, or your local library catalog, the option to reduce the results to those most relevant to the user is an important one.
If you subscribe to Firstsearch for inter-library loan purposes only, you may be able to substitute Worldcat.org, though there are more sophisticated search options available via Firstsearch. Public libraries will want to maintain their Firstsearch subscription, otherwise their holdings won't display on Worldcat.org.
