The aliases are the entity's name with and without its space and its host. The University of Michigan (its administrator), Google Books and the Internet Archive (sources of its scans; the Internet Archive a row of its own in the census), the HathiTrust Research Center (a part, a row of its own, htrc) and HATII (Wikipedia's disambiguation) are distinct entities and are not aliases; the HTRC pattern sits in class (3) because the field sources the Center's analysis as the class's instance for the entity. The census area 'corpora' ('collections, crawls and datasets whose texts enter machine training') places the entity in the census's survey, and the census itself records that the saved sources say nothing of training use; no class of training corpora is sourced for the entity. The census's tll_reading is the archive's reading, ledgered as TLL-NN. #186 and #1543, the census's anchors, are read at the passages on corpora, the training loop, machine reading and inspection. Admission by reading (§3.4): D where a deposit names the entity and says something of it (its holdings, its access, its refusals of the archive's requests, its kind); R where it states a relation between the entity and an archive object; O-class where a sentence applies an archive category to one of the three classes; a bare mention, a citation line or a catalogue link is not a claim.",
