Easily one of the most engaging and educating books about type.

The Elements of Typographic Style by Robert Bringhurst.

Required reading for designers, typographers and anyone in the industry. It's slightly lost its status in the internet age with a lot of designers doing web work now, but it still remains one of the most influential and important texts on the subject. Herman Zapf was quoted as saying "I wish to see this book become the Typographer's Bible". Doesn't come much better endorsed than that.

Even though it's somewhat hard to get hold of, it's still a course text for a lot of design schools.

Awesome, I just both this two:

cant wait until they here! Thanx a lot for the nice suggestions.

If she doesn't have it already, The Elements of Typographic Style is probably a must-have.

I agree with Mr. Hamburger that the documentary Helvetica is a good choice, too. They have some other assorted Helvetica merch in their store.

If she's got a bit of a sense of humor, I think a keming shirt would work as a less-scholarly gift.

Perhaps a bit frivolous, but this is a neat little pop-up book called ABC3D.
