CZ:Direct referencing

By direct referencing, we mean that a reference has its own page here at Citizendium, e.g. at CZ:Ref:DOI:10.1016/0301-0082(89)90013-0 (to which CZ:Ref:Hofman 1989 On the evolution and geometry of the brain in mammals redirects). This way of referencing deviates from usual wiki habits (in which the same reference would be provided as a footnote to the page that references it, see below) but is assumed to be more convenient for online reading, particularly if the references are labeled such that they can be easily identified by informed readers in the context of the referring article (e.g. as Hofman 1989).
