Today I stumbled upon this Hybrid Classes page (d20pfsrd) and since I once bought a few pathfinder source books in PDF I went to see if I already own the relevant book (I usually play liberally-houseruled versions of 3.5e).
Sadly, the only Pathfinder rule-book I own is the Core Rulebook (the others I own are guide-books, bestiaries, and adventures).
In what source books do hybrid classes appear?
What about the base classes?
Are they available as PDF? Print? Both?

These books are all available in print from a variety of sources (except the World of Vampire Hunter D book), including Amazon, directly from the publisher (Paizo), your FLGS, and possibly in normal large chain bookstores (though availability there will be pretty hit-or-miss). The PDFs are, to my knowledge, only available directly from Paizo.
