Text Mining & Computational Text Analysis: Library Sources

Library Resources for text analysis: Large collections and platform-wide access

Many library-licensed online resources do not support text mining applications. The publishers, vendors, or collections listed here are exceptions, and offer some mode of access to texts for large-scale analysis. 

Library Resources for Text Analysis: Smaller collections and individual publications

Library Resources: Available by request

Text mining access to the following resources will require mediation by the Library and vendors involved. Researchers should expect to provide a description of their research, and depending on the scope of the request there may be associated costs. Please contact for more information.

Gale Digital Collections
Request access to Gale content for text analysis purposes, including access to OCR text from databases like the Eighteenth Century and Nineteenth Century Collections Online, as well as content from Gale’s newspaper archives. See Gale's FAQ (pdf) or brief description for more information.

Adam Matthew Digital
Contact History Librarian Jennifer Dorner ( to request access to OCR text and full metadata from any of Adam Matthew Digital's primary source databases.

Please scrape responsibly

Using Python, Selenium, or other programmatic tools to scrape database search results (even cleverly) can result in access being shut down for the entire campus. : (

What is text mining?

"Text Mining is the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources... The difference between regular data mining and text mining is that in text mining the patterns are extracted from natural language text rather than from structured databases of facts."

- from What is Text Mining? by Marti Hearst (2003)
