The aliases are the entity's English and Dutch names, its abbreviations IISH and IISG (case-sensitive), and its hosts (iisg.amsterdam, iisg.nl, socialhistory.org). The Royal Netherlands Academy of Arts and Sciences (KNAW), its Humanities Cluster, the IISH Foundation, the Netherlands Economic History Archive (NEHA), the ESSHC and Nicolaas Posthumus are entities distinct from the institute (its academy, its cluster, the owner of its collections, an archive it houses, a conference it organizes, its founder); none is an alias. #1725, the census's anchor, is read at the passages that name the kind (the organ, the holder and the route by which a defeated critique is carried forward; the Hague expulsion of 1872; the critique that no one holds): its 'holder' is a role in an organization, and the census's ml_reading ('a holder in #1725's sense') is the archive's reading, ledgered as ML-NN, not a class. Admission by reading (§3.4): D where a deposit names the institute and says something of it; O-class where a sentence applies an archive category to one of the four classes; a bare mention, a reference line, a URL or a list of keywords is not a claim.",
