Yeah, there are several.
The first would be "Original MGB with MGC and MGB GT V8" by Anders Clausager. This book has incredibly detailed photography on every aspect of the B. It's great if your working on your car and need a good reference of how it should look.
"MGB, MGC & MGB GT V8" by David Knowles is another. This book has more information on the history of the car and is more subjective.
Although I have several others, I don't have "MGB The illustrated history". It's supposed to be a pretty good book.
There are others as well and a host of technical books. You can check them all out on mossmotors.com.
