    I toiuched the formatting and the hyperlinking of the paragraphs on compatibility of limits with other universal constructions.

    Merged the previous tiny subsections on this to a single one, now Compatibility with universal constructions.

    added the hyperlink to the stand-alone entry adjoints preserve (co-)limits.

    Will create an analogous stand-alone entry for limits commute with limits.

    Added the original reference that defined limits. Truly bizarre that after 75 revisions this article does not have a single reference.

    I find that paper of Kan amazing. Out of the blue, these fundamental and extraordinarily deep concepts of category theory are presented clearly as if on a tablet handed down by a God. I think that there must have been some background to the paper; in places, Kan’s wording suggests to me that the terminology might not be his (perhaps Eilenberg’s?). Thus the concepts may have to some extent have been extant. It would be a great job for a historian of mathematics to try to understand where the ideas came from.
