Durie A & Magee K (2008) Come North: Glassert Game Books and Diaries. Forth Naturalist and Historian, 31, pp. 117-119. http://www.fnh.stir.ac.uk/journal/back_issues/vol_31/75-120.pdf
First paragraph: Through the kindness of the Joynson family, the archives department of the University of Stirling has acquired some very interesting material from the Glassert estate at Aberfoyle. This is the first instalment, or so it is hoped, of what will be a much larger deposit of estate and family papers, and it certainly whets the appetite for what may follow. There is one personal diary for the year 1885, which rather stands in isolation, and five game books; two from the later nineteenth century (1874-1878, and 1885-1886,) and three from the second quarter of the twentieth century; 1925-1935, 1935-1939, and 1940-1942.
