As well as extensive notes at the back of the book, there is also a highly readable introduction by Adam Watt.
Lisa Hill, ANZ LitLovers
[An] excellent introduction (supplemented by copious notes) [by] the Proust specialist Adam Watt.
Adrian Tahourdin, Times Literary Supplement
[...] this new translation which concentrates on [Swann's] infatuation for Odette is a gentle and accessible introduction to Proust's monumental oeuvre, being quite self-contained and not nearly so daunting a read.
Robert Tanitch, Mature Times
