"Tricks of the Mind" by Derren Brown also has some basic information on memorization, along with a host of other interesting topics.
I listened to it while working out over the course of several weeks and, despite not putting much effort into it, was able to improve my ability to remember short lists (e.g. groceries) and names. With more focused practice, I'm sure it would lead to excellent results.
The only flaw in it is that some of his social references are a bit dated. In the imagery exercises, you'll probably want to substitute your own, updated names and faces. :-)

1: candle, 2: swan, 3: handcuffs, 4: sailboat, 5: curtain hook, 6: elephant’s trunk, 7: boomerang, 8: snowman, 9: balloon and string, 10: stick and hoop
Combining it with the journey method helps remember longer sequences. The funny thing is that you might remember the number two by imagining a giant swan in the next room. When you don't need to remember it anymore, you imagine yourself throwing a grenade into the room and blowing up the swan. It really works!
Darren Brown's Tricks of the Mind is generally about his life history in becoming a mentalist, but it has a lot of fun tidbits about methods to get over traumatic memories, amp yourself up for things you don't want you to, defuse arguments/fights, and it was the first place I ever heard of memory palaces.
