Bookworm

HathiTrust Research Center's Bookworm tool charts trends in word use from 1500-2015 in hundreds of thousands of texts in HathiTrust. Filters are available for subject classification, fiction/non-fiction, genres, language, format, page and word counts, and publication information. Controls allow choice of date ranges, different metrics and case sensitivity.

Bookworms based on other text collections are available at http://bookworm.culturomics.org/.
