The lwb of the Hermetic has information on the symbolism used in the cards and is quite good - especially for a lwb
I think any book that deals with a Golden Dawn deck will have useful information - for example good books on the Thoth or Wang's Golden Dawn Tarot, as these decks follow the same system.
I got The Qabalistic Tarot by Wang as someone recommended it as a good reference book for the Hermetic, but the Hermetic Tarot is not even mentioned in this book, it uses (among other decks) the Thoth and the Golden Dawn Tarot.
