This I my lament…I do bemoan the end of footnotes.
Pages may have looked more cluttered, and there have been instances where there are more footnotes than text space on any given page – the worst example in my library is Joachim Marquardt's Das Privatleben der Römer, 1886 (reprography by Wissenschaftliche Buchgesellschaft, Darmstadt, 1990); in the olden days, I guess, publishers did do anything a learned author wanted.
However, I resent having to go to the back of a book for endnotes all the time, the more so when there are no page number references on top of the endnote pages. The latter should not be difficult in today's age of electronic type-setting. One pays enough for university press books and such anyway…
