Hi all,
I’ve recently learned that Zentralblatt and the Mathematics Reviews are collaborating to revise the Mathematics Subject Classifications (MSC) for 2020. The current MSC2010 codes were a revision of the original MSC2000 codes. You can read more about this here:

The editors of zbMath and MR are inviting suggestions from the community as part of this process and I think category theory should weigh in about the 3- and 5-digit subject classifications housed under “18.” This might not be the most important thing in the world but on the other hand, I could imagine working as a mathematician whose primary research area is (say) 55 or 3, searching for MSC codes to add to a paper before uploading to the arXiv, finding a particularly apt one under 18, and then gradually over many years of this starting to think of myself as a category theorist, in part, too.
I’d rather not be the one to curate feedback regarding the MSC codes but if no other volunteer presents themselves, I’ll at least send an email summarizing the discussion that takes place here.
thanks for volunteering ; - ) it seems to me that there needs to be a section 18Hxx for Higher Categories, under which all higher-dimensionl CT falls, classified by appropriate subsections like: 2- and Bicategories, Quasi-Categories, Strict n-categories, Double Categories, etc. Steve [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
