Oh, to laugh, to laugh. “Revenge of the Librarians” is that rare comic collection, funny yet never dumb. Aiming at every conceit and hapless circumstance of the modern author, Tom Gauld and his deliciously detailed and distinctive strips veers from slapstick to bitter irony, somehow always laced with compassion. Laugh out aloud at “some useful abbreviations for the time-pressed online author,” chuckle at the pandemic-locked-down bookshop cat, join Godot as he waits for a Zoom meeting, use the “thriller concept generator.” Savor one a day and Revenge of the Librarians will bless you with six months of intelligent pleasure.
