A pretty solid collection of essays, with a rather heavier emphasis on providing a factual outline of the Beatles' career than on providing criticism or analysis, though it does have the latter. Decent and (mostly) competent, and a useful synthesis of an array of sources that would be a good introduction to the subject.
(I say "mostly" competent largely because of the second essay in the book, "The Beatles as Recording Artists" by Jerry Zoltan, which has a number of errors ranging from the trifling and baffling (saying that people misheard the "cranberry sauce" at the end of "Strawberry Fields Forever" as "Paul is dead" rather than "I buried Paul"; claiming that "Something" has an "unusual structure", when it has a very simple AABA'A pattern) to the more serious and nearly alarming (misattributing "Back in the U.S.S.R." to John Lennon and "The Continuing Story of Bungalow Bill" to Paul McCartney, when it's exactly the reverse; claiming that Paul played all the instruments on "Why Don't We Do It In the Road?", though Ringo played drums on it, as a glance at Lewisohn, MacDonald, or even Wikipedia would have confirmed). It's puzzling how an essay so far inferior to the others slipped in.)
