    Added link to Bourn’s most helpful 2017 textbook From Groups to Categorial Algebra : Introduction to Protomodular and Mal’tsev Categories. Revised reference to the Borceux-Bourn 2004 monograph.

    Incidentally, our entry histories (here) do not seem to record previous entry names.

    Here I suppose you changed the title “Mal’cev” to “Malcev”?

    But maybe give us a hint for why you did that. We might learn something. Earlier authors of this entry seemed to feel it’s important to spell it “Mal’cev”?

    (I have no idea about this.)

    Malcev himself used two spellings in his papers: Мальцев in his Russian papers and Malcev in his non-Russian papers.

    Hence, the renaming was performed to enable finding his papers using search engines and databases (especially those that get confused by apostrophes).
