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

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)
