Use Omni to discover books available through the library, whether they're ebooks or physical.
Omni even finds chapters within books.
Although our ebooks are included in an Omni search, searching them directly from the publisher site might provide a deeper search, finding your search terms at the chapter or page level.
There are hundreds of subject-specific encyclopedias, handbooks, dictionaries, etc. available through the library. Look for them in Omni.
Search within some of our large ebook packages. Some collections are specifically meant for background "reference" information.
