HathiTrust Access Basics
Access to items in HathiTrust’s digital library includes access for
Your access to HathiTrust items depends on a number of factors including whether or not an item is restricted by copyright, your geographical location, your affiliation with a member library, and your log in status.
HathiTrust is not a subscription service and does not license the content in the digital library for lending purposes. Instead, member libraries contribute digitized items for preservation and HathiTrust makes those titles available for you to access to the fullest extent allowable by law. Because of copyright law, no one is permitted reading access to copyrighted items in HathiTrust — including the member library contributing the copyrighted item — except when eligible through emergency access or services for people with disabilities.

HathiTrust Search Basics
You can access the search bar from every page of the website and digital library. Expand the search bar by clicking on the Search link in the site header. There are two basic options to begin your search:
Search the Website: Search the content of the HathiTrust information website using keywords. This DOES NOT include the digital library content that you find in the Collection.
Search the Collection: Search texts in the HathiTrust Digital Library collection using the methods listed below. By default, your search results will include all the texts that are available to you to access online — known as “Full View” — limited by the search terms that you apply. These titles are available for you to access because they are in the public domain or licensed as open access. To also include texts that are restricted by copyright in your search results, specify “All Items” under “Item Viewability.”
Search Using Keywords
- Keyword search allows you to search for topics, quotes, names, places, or phrases in both the information Website and the Collection.
Search Options in the Collection
- When searching the Collection you can search Full Text & All Fields to search all the text of all the volumes in the entire digital library including book information such as Title or Author.
- Narrow your search to only book information, such as Title, Publisher, and Author, by choosing All Fields indicated in the dropdown menu options. Use other specific fields in the dropdown menu when you know the exact Title, Publisher, Author, or other book information.
- Selecting Advanced Search allows you to select multiple fields for a combined search enabling more detailed searching.
You can also search inside collections of works that you or others have created (See Featured Collections). When reading a book, use keywords to search inside that volume.

Datasets: A full-text file of specified public domain items are available by request and may be used offline. HTRC also has several pre-made datasets that do not require approval for use.
Worksets: You can create a smaller collection of HathiTrust titles using the Collection Builder and then analyze using HTRC services.
hathifiles: Metadata describing all works in the HathiTrust collection are available for download as tab-delimited files.
Other Data: The Bibliographic API allows real-time querying against the HathiTrust collection on a known identifier for brief or full bibliographic records. Other data management tools can help librarians make HathiTrust items more discoverable.
