Wondering exactly how many times the mysterious word “Boojum” appears in The Hunting of the Snark? (3). There’s a pretty user-friendly and accessible concordance of seven of Lewis Carroll’s most important works – Both Alices + “Under Ground”, Snark, Slyvie & Bruno, The Game of Logic, and Phantasmagoria and Other Poems – at the Victorian Literary Studies Archive (in addition to searchable texts of dozens of other authors.) Thank you to the VLSA for making a useful website, and thanks to LCSNA member Lester Dickey for the tip.
