Sample Files
A sample of 100 extracted feature files is available for download through your browser: sample-EF202003.zip
Also, thematic collections are available to download: DocSouth (82 volumes), EEBO (234 volumes), ECCO (412 volumes).
Filepaths
The dataset is stored in a directory specification created by HTRC called stubbytree. (Note: This is a change from previous versions of the Extracted Features dataset that used the pairtree directory specification.) Stubbytree places files in a directory structure based on the file name, with the highest level directory being the HathiTrust source code (i.e. volume ID prefix), and then using every third character of the cleaned volume ID, starting with the first, to create a sub-directory. For example the Extracted Features file for the volume with HathiTrust ID nyp.33433070251792 would be located at:
