A few weeks ago I stated that there are too many Bob Dylan books out there.  Likewise, there must be hundreds of books written about the Beatles collectively and about the four individual members.  Paul Mccartney just announced in November he will publish a memoir titled "The Lyrics: 1956 to the Present."  This will be a two-volume 960-page opus that will examine 150 songs that McCartney has written.  Thus, it is not an autobiography.

Since this 2-volume set is coming from the songwriter, it should provide new insights.  Likely, it will read like a reference book.
