In Memoriam: Peter Nicholls, 1939-2018

His Encyclopedia of Science Fiction (co-edited with John Clute) will remain an indispensable guide to the SF-perplexed for decades after his passing; I can remember referring to a copy of it at the library at Northeastern Illinois University when I couldn't even buy a used copy, and the only book that might've caused me to check out the works of more SF authors was Baird Searles and Co.'s A Reader's Guide to Science Fiction, which I still own a badly dog-eared copy of somewhere; it's just that Searles' book comes off as a comparative light introduction while Nicholls' and Clute's comes off as definitive to the point of being obsessive.
