HathiTrust Access Basics

Access to items in HathiTrust’s digital library includes access for

  • Reading 
  • Searching 
  • Downloading
  • Researching

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.

Log in to HathiTrust

You are not required to be a member nor have an account to access HathiTrust. However, members who log in using their institutional login and password obtain the member benefits listed below. Individuals who create a Guest account to log in may also create and save personal collections. See a list of HathiTrust Member Libraries and learn how to log in as a member or a guest.

HathiTrust Access Chart

Everyone includes individuals, as well as independent researchers, journalists, and genealogists. Individuals are not eligible for HathiTrust membership.

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.

See the HathiTrust Help Center for more details on Searching the Collection.

Dig Deeper with the Research Center

The HathiTrust Research Center exists to help both novice and advanced researchers dig into the digital library. Access the tools below, as well as tutorials and other documentation, on HTRC Analytics.

HathiTrust + Bookworm

Visualizes word trends in millions of volumes held by HathiTrust. It enables scholars to discover new textual use patterns across the entire corpus, including copyrighted and public domain volumes.

Graph of the HTRC bookworm tool shows a single line tracing the history of a word's usage through centuries of published material.

Algorithms

HTRC Algorithms are click-to-run tools for text analysis. They require no programming, and researchers can set the parameters for their analysis. You can use algorithms to explore HathiTrust worksets, which are groups of titles from the collection. 

Explore More Data

To work with the collections’ data at a deeper level — from metadata contributed by libraries to the very words themselves — we offer data pathways for researchers and librarians.  We provide this data in a number of formats so you can discover, identify, interpret, or manage the content.

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.
