how do i know if a book is available for an inter library loan?
Normally the best place to start is in the WorldCat database, via the Omaha Public Library Resource Center tab (under Books and Reading): https://omahalibrary.org/resources/books-reading/. Search for your title, and the record that comes up will also tell you how many libraries hold the item, which can often be a good indicator of how easy it will be to get (few libraries mean few possibilities). That said, it's always worth trying (you just click on the Request this Item button and fill out the form). We will let you know if we can get it, or offer other possibilities.
That being said--unfortunately this particular book is a fairly rare genealogy book, and the 8 libraries that own it keep it in their non-circulating reference collections. However, there is good news! One of the library catalogs includes a note that the information in the book was extracted from LDS film #16969. That particular film has been both digitized and indexed and is available free here. Click on the little magnifying glass to the right of the film number for the index, and on the little camera to see the film itself.
I hope this helps! Let me know if you have any questions.
