I know a publishing house for books to primary schools, it was a one-woman operation (she wrote the books) which over a twenty to thirty year period  made her quite a few pennies.  She died a while back but the operation is on-going and still making money.  If your gf's books are in that area and if her copyright isn't owned by another company (MMM LLP sets forth) you could send me a copy of a couple, I'll pass them on(1).  

(1)I have no say in editorial decisions --and so far the company only produces the woman's books.

(you could slip a CD into that package, too.(2))

((2)I only type that to encourage your inner and outer artist.(3))

(((3) If you can get it to me before, say, the end of the second week of Christmas I can send it on to another person who (I think) will be interested.(4)))

((((4) When I say "I think will be interested" I mean that I am supposed to be sending him something and I'm thinking that he might be interested in the combination)))
