Hathi Trust Digital Library

[Speakeasy]

Recently, a fellow member on the HTLAL provided me with a link to some older language-learning materials on the Hathi Trust Digital Library https://www.hathitrust.org/ an organisation with which I was not familiar. My subsequent G-search of the HTLAL revealed only four discussion threads in which a specific reference was made to this online library and, in all cases, the comments related to the archiving of some old, if not very old, materials. So then, I was wondering anyone might comment on how they have used this library for locating specific or generic language-learning materials and what "tricks and traps" they might wish to pass along. Merci à l'avance!
