HathiTrust is a partnership of libraries that works towards the goal of developing a shared digital access, preservation, and storage solution for the materials held in the member libraries.
You have three search options on the HathiTrust Digital Library main search page.
1. Catalog Search: search for materials by author, title, subject headings and source.
Also try the new WorldCat Local Prototype catalog, the first version of a HathiTrust built on OCLC's WorldCat Local interface. From here you have access to the HathiTrust Digital Library AND to OCLC’s database of worldwide library collections. From any record, see the “Find a copy in a library” section to see which libraries hold a print copy of the item. You can also limit your search results to volumes that are only full view or limited view, using the “View” facet on the left hand side of the search results screen.
2. Full Text Search: searches each word in the text, whether or not the full text is available for download, and you will find the pages on which the term(s) appear. You can then locate a library that holds the item, and request it via InterLibrary Loan.
3. Collections Search: you can search for materials that you or others have grouped into "collections". Users can create "private" or "public" collections from materials they find in the HathiTrust Digital Library. If a library adds a special collection of digital materials to HathiTrust, this is how the collection can continue to have a separate identify within the whole Digital Library.
