My collection is a bit smaller than yours, Keri...
1) The Beatles Forever- Nicholas Schaffner : When this book was published in around 1977, there weren't many as comprehensive as this. Granted, there are no direct interviews and some of the facts have been subsequently proven to be wrong, but this was an entryway into the Beatles minutia for me.
2) The Beatles Illustrated Record- Roy Carr & Tony Taylor : Checked out from a library, then bought. Album by album reviews by guys who were around at the time of issue. Full of album details....published right after Lennon's death, it is full of praise for John at Paul's great expense. Caused me many years of ignoring Paul's solo work. Still the Beatle album reviews are great.
3) The Beatles' Recording Sessions- Mark Lewisohn : NOW we're talking! This one treats the Beatles' work more from a historian's perspective, so it was aimed right at me! :-) Every Beatles recording session in fine detail, who played what on every Beatles recording session, taken right from EMI's recording sheets that were written at the time.
4) A Cellar Full of Noise- Brian Epstein : Agree with your review of this one, Keri. Maybe a bit sanitized, but he was pushing the Beatles to the world.
5) The Beatles- Hunter Davies : Nice book with some details one couldn't get anywhere else at the time.
6) Many Years From Now- Barry Miles : If one wants details from McCartney's point of view, this is the book for that. Extensive...
7) All These Years- Mark Lewisohn : Totally agree with Keri about this unbelievably detailed book.
In His Own Write/ A Spaniard In the Works- John Lennon : I must re-read these, as I read them as a teenager and didn't get much out of them.
9) Here, There & Everywhere- Geoff Emerick : Loved this book despite its inaccuaracies about actual dates and some facts. Geoff's insight into the recording process is fascinating.
10) All You Need Is Ears- George Martin : I've heard some say it's not cool for the Beatles' fellow travelers to "cash in" on their experiences. I disagree....I leard a number of things about the Lads from this book, but I was glad that wasn't the only chapter in this guy's life. His knowledge of the recording process spans from the earliest days of tracks on wax thru to the dawn of the digital age.
I'll dig a bit deeper and see if I've missed anything... :-)
