I was trying to get a book on Worldcat, but do not know how it works. Can you help.
Thanks for your question! Worldcat is a general database that shows the catalog items from thousands of participating libraries. As such, it is mainly used by our patrons for interlibrary loans. This is when another library would send us a book in the mail that we ourselves didn't own so a patron could check it out.
As such, what you get in Worldcat's listings are simply the library cataloging information for a particular item - even if it is an ebook - but not the book itself.
We could always try to get the physical book for you via interlibrary loan, but library ebooks usually are only available to that library's patrons and not transferable. The Omaha Public Library does have ebooks of our own that you could download and read on a computer or tablet, but obviously we can't have everything.
If you would let us know which title you were interested in, we can probably find some way to get it to you. If you know the author as well, that would help us find it.
I hope this answers your question and please let us know if we can assist you further.
