I am wondering what options there are for maintaining a list of errata / minor misprints / clarifications to published research papers. Here, I mean errors/misprints that are not sufficiently serious that a journal would consider publishing an erratum, but whose correction would nonetheless be beneficial to readers.
I have in mind a system where authors (and possibly readers) can attach comments / list of corrections / clarifications to their papers in a straightforward way - ideally in a way that links to the relevant DOI / arXiv identifier.
It seems somewhat surprising that such a system is not already established - or perhaps it is and I have missed it? One concern is over the longevity of the system - I used to maintain some errata to my paper on my own wiki-style pages, but at some point this wiki folded and I lost all of the information (which I had unfortunately not backed up anywhere).
