As most people probably know, the journal "K-theory" used to be published by Springer, but was discontinued after the editorial board resigned around 2007. The editors (or many of them) started the new "Journal of K-theory" in collaboration with Cambridge University Press.
Maybe I'm being very stupid or missing something obvious, but I am quite sure that articles from "K-theory" used to be available online via Springer, and as far as I can see they are no longer there. Did I miss something here, or did they just disappear? I can't believe Springer would do that, but then I can't find anything by searching, and the article links from MathSciNet are dead:
Sorry, the page you requested is unavailable. The link you requested
might be broken, or no longer exist. SpringerLink is providing
researchers with access to millions of scientific documents from
Journals, Books, Protocols and Reference works.
In case it helps, here is the journal ISSN: 0920-3036 (print version) 1573-0514 (electronic version).
Grateful for any clarification.
