Article 42

42.1. Interested institutions, in particular those with expertise in nomenclatural indexing, may apply for recognition as nomenclatural repositories under this Code. A nomenclatural repository takes charge, for specified categories of organisms, of registering nomenclatural novelties (Art. 6 Note 4) and/or any nomenclatural act (Art. 34.1 footnote).

42.2. Applications for recognition as nomenclatural repositories for organisms other than fungi (for fungi see Art. F.5.3) are to be addressed to the General Committee, which will refer the applications to the Registration Committee (see Div. III Prov. 7.13) and act upon its recommendation. Prior to such a recommendation, mechanisms and modalities of registration, and definition of coverage, will be developed in consultations among the applicant(s), the Registration Committee, and the Permanent Nomenclature Committee(s) for the group(s) concerned, and be widely publicized in the taxonomic community; a public trial run of at least one year must have shown that the procedure works efficiently and sustainably. The General Committee has the power to suspend or revoke a granted recognition.

42.3. Registration may be proactive and/or synchronous and/or retrospective; that is, it may occur before and/or simultaneously with and/or after the valid publication of a nomenclatural novelty (Art. 6 Note 4) or the effective publication of any nomenclatural act (Art. 34.1 footnote).

Note 1. For ways in which proactive registration of nomenclatural novelties functions, see Art. F.5.1 and F.5.2, relevant for names of organisms treated as fungi, including fossil fungi and lichen-forming fungi.
