Sonja Lang

4 titles are catalogued under more than one form, which is to say the registers hold them both as a work and as a distinct object, score, recording or edition. Where a title is documented in several forms the evidence behind it is correspondingly wider, and the article treats those forms as separate records of the same work rather than as separate works. Toki Pona, dated 2001 — catalogued as constructed language, a posteriori language, artistic language, modern language, philosophical language and engineered language. Sitelen Pona, dated 2014 — catalogued as constructed writing system, logographic writing system and Toki Pona writing system. The Language of Good, dated 2014 — catalogued as version, edition or translation and literary work. Toki Pona Dictionary, dated 2021 — catalogued as literary work and version, edition or translation.

These are texts written by the subject, distinct both from writings about the subject and from printed editions of other people's work. 6 works carry dates between 2001 and 2024. The run opens with Toki Pona — 5 catalogued parts and closes with The Wonderful Wizard of Oz (Toki Pona edition). The 2020s are the densest part of the run, with 4 titles, and that concentration is a fact about what the registers have catalogued rather than a judgement on the work itself. They belong to a run of 8 titles in all, from 2001 to 2024.

2 further works are catalogued under Lang's name without a date the collections agree on, which is why they are set apart from the dated run rather than placed in it. They belong to a run of 8 titles in all, from 2001 to 2024. Lipu su.

An authority file is a statement of identity, not a source of facts: it tells a reader that the Lang named here is the same person the register catalogues, and it is what allows the material above to be gathered under one heading rather than several.
