Introduction

The HTRC releases research datasets to facilitate text analysis using the HathiTrust Digital Library (HTDL). While copyright-protected texts are not available for download from the HathiTrust, fruitful research can still be performed on the basis of non-consumptive analysis of features extracted from full text. To this end, the HathiTrust Research Center (HTRC) has makes available page-level features extracted from volumes in the HTDL. These features include volume-level metadata, page-level metadata, part-of-speech-tagged tokens, and token counts. Additionally, the HTRC has partnered with advanced researchers to release a derived dataset, Word Frequencies in English-Language Literature, 1700-1922.
