THE LIBRARY, SIGNED OUT, 2026-11-01, AI MODE: 'The HathiTrust Digital Library is a massive, large-scale collaborative digital repository containing more than 18 million digitized volumes. Founded in 2008 and administered by the University of Michigan, it functions as a partnership between major global academic and research institutions to preserve the cultural record and provide long-term access to the public good.' Key features (collection size; public domain access, 'roughly 7 million volumes'; copyrighted materials 'still fully text-searchable'; diverse sourcing; 'HathiTrust Research Center (HTRC): Offers text-mining and computational analysis tools for researchers'); how access works (a table of the general public and logged-in members against public-domain and copyrighted material); tips (log in early, the Accessible Text Request Service, bot protection); a follow-up offer. No source cards: seven inline chips (HathiTrust, Wikipedia, University of Michigan Library, YouTube). The query is not in the paste; it is the census name, as the split manifest records. The two web results above the answer are kept in the raw paste.

Reading

The innocent reading first. Asked for the library by name in AI Mode, the composer says what it is, who founded and runs it, how large it is, where its scans come from and what each kind of user may do with them, and offers instructions for search or text mining.

Findings

THE REPOSITORY AT ITS GRAIN. 'Founded in 2008 and administered by the University of Michigan' agrees with Wikipedia ('administered by the University of Michigan', 'founded in October 2008'). 'Over a third of the collection (roughly 7 million volumes) is in the public domain' rounds Wikipedia's 'more than 18 million volumes, including 6.7 million in the public domain in the United States', and drops 'in the United States', the condition on which the census row's international restriction rests ('access is also restricted for users outside the United States to works published outside the United States after and including 1896'); the composition's public domain is 'fully available for anyone worldwide'.
THE SOURCES OF THE SCANS. 'the Google Books Project, the Internet Archive, Microsoft, and member institutions' local scanning projects.' Wikipedia: 'content digitized via Google Books and the Internet Archive digitization initiatives, as well as content digitized locally by libraries.' Microsoft is on no saved HathiTrust source; the census row's Internet Archive evidence records Microsoft's Live Search Books as a contributor to the Internet Archive.
THE RESEARCH CENTER IN THE PRESENT TENSE. 'HathiTrust Research Center (HTRC): Offers text-mining and computational analysis tools for researchers to perform advanced data analysis across the entire digital corpus.' The HTRC home page, saved the same day: 'HTRC has discontinued its services as of September 30, 2026. HTRC accounts are no longer available.' and 'HTRC Algorithms and Data Capsule services have also been discontinued.' The follow-up offers 'precise instructions on how to use their Advanced Search or text-mining tools'. The census row gives the Research Center's computational analysis as 'ended 30 September 2026'.
THE SEARCH WITHOUT ITS RULING. 'Items under copyright are still fully text-searchable. Users can search the entire corpus to see how many times a word or phrase appears and find corresponding page numbers.' The census row reads this search as the record's precedent, from Wikipedia: 'finding that HathiTrust's use of books scanned by Google was fair use under US law' and 'providing search and accessibility for the visually impaired were grounds to consider the service transformative and fair use'. The composition gives the search and the Accessible Text Request Service ('Patrons with certified print disabilities') as features, and Authors Guild v. HathiTrust, the ruling that holds them, is absent.
NO PERSON AND NO FOUNDERS. The census row names the executive director, 'The executive director of HathiTrust is Mike Furlough,', the 219 member libraries and the founders, 'the twelve universities of the Committee on Institutional Cooperation and the eleven libraries of the University of California'. The composition names partner universities only as places to log in ('University of Michigan, University of Wisconsin, University of Calgary, or even NYPL cardholders') and no person.

Analysis analyst prose, not machine text

The repository composed at its grain, with its access tiers, from its own site and the Michigan library guide. Its research center is offered as a working service a month after its own home page records the end of its services, and the fair-use ruling the census row reads the search by is absent.
