WorldCat

What is WorldCat? It's the world's largest network of library content and services, and it can be found at worldcat.org. Many libraries in the US make their card catalogs available to the WorldCat search engine, so someone looking for a rare book can find out what libraries have copies and work out an inter-library loan agreement with their local library to obtain a copy to check out.

Now, how is WorldCat useful to authors? We can use it to see how many libraries have copies of our books in stock, which gives us an idea of our library sales. Not ALL libraries participate, but enough do to make the search worthwhile, especially for authors whose publishers focus on library sales, like Five Star Publishing does. When I searched for my book, A Real Basket Case, today, I found that 46 library systems have copies and some of those have multiple copies. I consider this to be good news, given that my book was only released on March 21st.
