A book by
Polish author Stanis{\l}aw Lem. A collection of reviews of (mostly) fictional books,
A Perfect Vacuum satirises and
parodies everything from the
noveau roman to
pornography to
Ulysses. Lem starts, appropriately enough, with a review of
A Perfect Vacuum itself.
Has been compared (including by Lem himself, in the autoreview) to some works of Jorge Luis Borges.
