I finally saw the reprints yesterday at Borders; they had Indiana Jones and the:
... Seven Veils
... Genesis Deluge
... Sky Pirates
... White Witch
... Philosopher's Stone
... Hollow Earth
... Secret of the Sphinx
I haven't seen the other five, but I also have other bookstores to check (though I'm just looking out of curiosity; I already have old printings of all of them, and I don't want to pay full price for a complete set of them again just to have extra copies - if I can find nice used copies, though, I'll snatch them up).
I find it a little odd that they had three or four copies of each of these, yet not a single copy of any of the other five. To me, that implies they've gotten just these in and not the others, but why would they not stock the full series (especially when it is a series, with continuing storylines from book to book, at least within each author's run)?
