Hi. I wanted to provide some feedback on the following page:
Where it says:
A distinct ISSN should be supplied for each distinct version of a title. If a title changes significantly the publisher should obtain new ISSNs (both print and online). This rule is established by the ISSN International Centre, not us, but we support and enforce it. Minor title changes (such as changing ‘and’ to ‘&’) don’t require a new ISSN.
The docs could mention that ISSN does allow for a “parallel title” in addition to the “title proper” for a given ISSN, for example:
ISSN 1878-7304 (Online) | Canadian psychology | The ISSN Portal
Title proper: Canadian psychology
Parallel title: Psychologie canadienne
Furthermore, swapping parallel and proper titles would not affect the ISSN, as per ISSN Manual:
A new ISSN and a key title are not assigned in cases of minor changes in the title proper. In general, if a minor change occurs in the title proper, the later title is given as variant title. The following are to be considered minor changes:
g) The change is in the order of titles when the title is given in more than one language on the chief source of information, provided that the title chosen as title proper still appears as a parallel title;
South African medical journal
Parallel title: Suid Afrikaanse tydskrift vir geneeskunde
Suid Afrikaanse tydskrift vir geneeskunde
Parallel title: South African medical journal
Fortunately, it seems it’s only a documentation issue, as the CrossRef Title List already recognizes title variants.
I’ve just asked the ISSN national authority to include a parallel title and now I wonder if they will get automatically reflected in the CrossRef Title List or if it should be requested separately?
