The Bob Dylan Encyclopedia isn't so much a comprehensive reference work as just an alphabetical listing of stuff that the author wants to say about his favourite musician. There is no entry for "Maggies Farm" or dozens of other songs that most readers would consider essential for any Dylan encyclopedia. There is however an entry for "Early Morning Rain" a Gordon Lightfoot cover which Bob recorded for Self Portrait, along with 7 pages dedicated to "Angelina" an obscure track from Shot of Love (which means it warrants four times as many words as the entry on Joan Baez). There are esoterically entitled entries such as "Blues , inequality of reward in." "Book endorsements, unfortunate" and "frying an egg onstage, the prospect of" which are thrown in because it's Gray's book and he can do what he wants.
This would be simply maddening if the writer concerned wasn't Michael Gray. Mr Gray has fully immersed himself in his subject matter for decades and knows Dylan backwards. He's noted for his "depth of research into Dylan's sources" as he modestly says himself in his own entry in his own encyclopedia. Gray doesn't just know Bob, he knows the blues, the bible and the folk traditions that inspired Bob at the start of his career and every year since. Entries like "Film dialogue in Dylan's lyrics" make it clear that Gray has every word of Bob's catalogue lodged in his brain and even when he's watching a movie he's looking for Dylan connections. When Bob sings "Somebody is out there, beating on a dead horse" he might be referencing the movie version of Catch 22, as Gray suggests, or he might not. Either way it's fascinating to see Gray's mind at work.
Equal to Gray's extensive research is his body of forthright opinions, which he is never reluctant to share. He spares no punches in his entry on his rival Clinton Heylin, whose work he praises but whose "notorious belittling" he clearly blames for the fact that they don't get on. Gray is also quite prepared not to mince words when criticizing the subject of the book, describing songs like "John Brown as "wretched" and "Mutton-headed, mawkish and crass."
The Bob Dylan Encyclopedia is undoubtedly self-indulgent but Gray's knowledge, opinions and writing styles are worth indulging in. I'd recommend Song and Dance Man III, his more systematic work, before I recommend this, but but for the true Dylan obsessive, this is a long strange trip indeed and worth taking.
