HathiTrust is a library catalog containing scanned full text of millions of published works owned by large libraries. Works that were published by the federal government, were never copyrighted, were made public by the copyright holder, or have "aged into" the public domain may be accessed fully. Works that are protected by copyright can be searched but not accessed in "full view." Those works can be found at libraries and obtained as print copies via FindIt@MU links to interlibrary loan forms.
Worldcat is the closest thing we have to a comprehensive catalog of all library holdings in the world. If a book is owned by any library, you will find a record for it in Worldcat, and if MU does not own it, you can usually borrow it using interlibrary loan links.
International catalog containing over 95 million records of books and other materials held in libraries worldwide. Titles unavailable elsewhere can be requested here.
