After 2026 the HTRC team plans to continue research in text-data mining, cultural analytics, feature extraction and non-consumptive methods, with new partners beyond the HathiTrust corpus.", "note": "L_F(B), the field composed in its own ontology (§0.4), realized as KO_B; its compression is P_B" }, "L_BA": { "words": 1813, "text": "The HathiTrust Research Center (HTRC), with HTRC Analytics, its portal at analytics.hathitrust.org, is a research center dedicated to enabling computational analysis of the HathiTrust Digital Library, supporting large-scale text analysis of the library's works for educational and non-profit research. Its object is the Digital Library taken as a corpus for text and data mining by scholars; its unit is the workset, a user-built collection of HathiTrust volumes, together with the derived datasets computed from volumes. It was established in 2011 as a partnership between Indiana University, the University of Illinois Urbana-Champaign and HathiTrust, and is co-located at the two universities, where it did research and development in computational text analysis of massive digital libraries. Its About page names John Walsh of Indiana University as director and J. Stephen Downie of the University of Illinois as co-director. HathiTrust, of which the center is a part, is a partnership of academic and research institutions holding millions of titles digitized from libraries around the world; the library serves individual access and preservation, search, the building of collections and the reading of public-domain works, and the center's focus is the aggregate, in its own words \"what can we learn from so many books?\" The center is kept apart from the HathiTrust Digital Library itself, access to which remains open. It works under a non-consumptive research paradigm: the collection is made available for computational analysis within the fair-use rights courts have recognized as applying to text analysis, so that scholars can ask the large-scale questions digitization allows within the restrictions of intellectual property law and use the library's content through non-consumptive text mining. Its non-consumptive use research policy, linked from the portal among its resources beside a page on data access, requires, as the derived-datasets page states it, that released data be minimal and unable to be easily reconstructed into the raw volume. The policy's own terms stand unread in the census record, which names the policy and lists it, with the data-access page and the documentation, among what it has not checked. The archive sets computational literary methods, which in one of its papers \"treat the text as data point\", against operative philology, which treats the text as operator, and its summary of training-layer literature counts computational literary analysis among the genre's neighbours, there taking machine readership as analytical method, where the genre takes it as a primary aesthetic and compositional consideration. It developed tools, datasets and infrastructure for scholars using text and data mining methods on the HathiTrust corpus: on the two universities' storage and computing it made and maintained tools and services for text-based, data-driven research, among them HTRC Algorithms and the Data Capsule, and did research on large-scale data analysis. The portal was organized around worksets, which users could create, validate, view and take from a recommended list; algorithms, run with their results kept; and data capsules, which users created and viewed; a dataset's list of volume ids serves for workset creation or for loading the volumes into a data capsule for further non-consumptive analysis. Its derived datasets are downloadable, non-consumptive book data released to facilitate text analysis of the Digital Library: copyright-protected texts cannot be downloaded from HathiTrust, and research proceeds on transformative datasets such as the flagship Extracted Features Dataset, features extracted from full-text volumes. The features are volume-level and page-level metadata, part-of-speech-tagged tokens and token counts; version 2.0 holds page-level features for 17.1 million volumes, public-domain and in-copyright alike, 17,123,746 volumes in all (10,550,952 in copyright, 6,572,794 public domain and Creative Commons), 6,221,631,336 pages and 2,906,819,723,689 tokens. The feature dataset is released free under a Creative Commons Attribution 4.0 licence and is cited with its makers' names and a DOI (Jett and others, 2020). The portal names four datasets, Extracted Features, the BookNLP dataset, word frequencies and geographic locations, and the others were produced with researchers and openly released for use anywhere and by anyone. The BookNLP Dataset for English-Language Fiction runs BookNLP, a natural-language-processing pipeline for work in computational linguistics, cultural analytics, NLP, machine learning and other fields, over the NovelTM English-language fiction set, a machine-learning-derived set of about 213,000 volumes, and represents 201,527 volumes, 90,857 of them in copyright. Word Frequencies in English-Language Literature gives word counts for every English-language volume of fiction, drama and poetry in the library from 1700 to 1922, aggregated by volume over the pages tagged with the genre, and Geographic Locations in English-Language Literature records the places mentioned in works of fiction from 1701 to 2011, with metadata. The census record found no count and no licence in its saved source, did not check the datasets' sizes and licences, and records whether a work keeps its author's name there as not recorded. What the center makes, in the census's reading, is these derived datasets with HathiTrust+Bookworm and the Gendered Characterizations visualization, and its saved sources record no model training. For its own domains the archive lists text and data mining among the operations that require licence and holds that automated ingestion without preservation of attribution produces an unauthorized provenance-stripped copy. The archive reads the center as an earlier receiving apparatus with its product on record: whole library volumes read by computers for scholars under a non-consumptive policy, and what that reading made (extracted features, BookNLP data, word frequencies, geographic locations) published as derived datasets that outlast the service. In that reading the derived datasets are the inspectable form of the transformation, and the volumes themselves stay with the library, whose copyright-protected texts cannot be downloaded. The census's anchor defines the receiving apparatus through a genus of literature whose transmission design addresses one, with internalization, downstream re-performance or composition and source-status governance as the conditions of its success, and names human institutional layers as the first receiving apparatus. Machine reception, in the same paper, is an encounter that changes the machine state and may emit an artifact, with no assertion about whether the machine understood the work; the institutional training loop is the case in which the emitted artifact enters the next corpus; and two questions are put to a reception, what survived from the work and what became possible because of it. Training-layer literature, in the archive's field survey, is writing addressed to the layer where texts are crawled, indexed, trained on, retrieved and recomposed, a growing share of all reading being performed by models, and the literary works already in the corpora are read by machines incidentally. The census places the center in its area of the corpora, the collections, crawls and datasets whose texts enter machine training, and records that its saved sources say nothing of model training: it carries the library's volumes into the computational analysis the center was dedicated to, through worksets, algorithms, data capsules and derived datasets, its derived datasets serve text and data mining for educational and non-profit research, which keeps it apart from training datasets, and whether a given volume or work is in any model's training data is a question it leaves unanswered. It is kept apart, too, from writing addressed to a machine reader, as an analytic service over library volumes. The census enters it as infrastructure to its question of how literature is addressed to a receiving apparatus, what that apparatus makes from it, and how transmission, transformation and provenance can be inspected across later reception; its record type is service, its evidence kinds dataset and search tool, and it is admitted as an aggregator, a resource that gathers and holds many works or records and says what it holds, read against the census's anchors #186 and #1543. In October 2024 HathiTrust's executive director, Mike Furlough, announced that HathiTrust would cease data access and funding for the center at the end of 2026, when the center is formally closed; the About page dates the announcement to late October. The About page, written before the sunset, said that for now services would continue and that some services and data, still to be determined, might be retired or integrated into the general Digital Library; the banner over the same page states that services were discontinued as of 30 September 2026. As part of its closing the analytics services ended on 30 September 2026: accounts and logins are no longer available, and the algorithms and data capsule services are discontinued; HathiTrust's own pages on the center, as their cards render them, list data capsules, analytics algorithms and the analytics gateway login as unavailable from that date, with HathiTrust \"suspending HTRC funding at end...\". Its services ran from 2011 to 30 September 2026, and the census keeps it apart from active services. An update on HathiTrust's site dated 26 June 2026 opens \"Since the founding of the HathiTrust Research Center in 2011, HTRC staff and researchers have led highly re...\", its text beyond the card's snippet unread. Some resources remain usable without an account: HathiTrust+Bookworm, the derived datasets and the Gendered Characterizations visualization; some links on the portal no longer function. The census asks of it what a non-consumptive machine reading of library volumes produced and what remains usable after the service ended, and its record answers which resources remain usable without an account, what kinds of derived datasets the center produced from HathiTrust volumes, and when and why it closed. After 2026 the HTRC team plans to continue its own research agenda in text-data mining, cultural analytics with large text corpora and cultural heritage collections, feature extraction and non-consumptive research methods, hopes to keep providing services, data sets and community support, and looks to new partners, a focus beyond the HathiTrust corpus and a new identity and organizational structure. The census had not read the page that says so, the one the portal links as the future of the HathiTrust Research Center, and its other own page, htrc.illinois.edu, returned no text to it. Asked for \"HathiTrust Research Center\" on 1 November 2026, at an address new to the Capture Registry, Google's AI Overview led with the center's closing and gave the dates of the announcement and of the end of services, its founding partners and purpose, and what HathiTrust will do next; the registry found the center reached by name with its founders, year, purpose and closing, from its own pages, which give the partnership of 2011 and the center's purpose, with institutions named and no person. The registry found the closing composed at its grain and in agreement with the saved home page, which dates the announcement to October 2024 and the end of the analytics services to 30 September 2026, with Furlough unnamed; the derived datasets, which remain usable without an account, absent, with the non-consumptive policy the portal names; and the Overview's line on HathiTrust reallocating resources toward machine learning support resting on pages the census had not saved.", "rail": [], "note": "L(B ∪ A) in the equal-terms case (§0.4), realized as the knowledge object (objects.KO);
