Tom Gauld loves books and reading so much. His new collection of comic strips Revenge of the Librarians is replete with love letters to books as physical objects and to all the people involved in producing and preserving them. Librarians, editors, bookshop clerks, and writers are each dealt with in multiple strips. The remarkable thing is how little rancor and bitterness is to be found within these pages. There’s sometimes weariness and, on odd occasion, despair. But neither are indulged in and both are dealt with with gentle irony rather than caustic wit. Gauld doesn’t seem to have a mean bone in his body.
