I am reading the Borges collection now (I'm assuming you mean the Collected Fictions translated by Hurley and published by Penguin) and it is great stuff - although I did have to ask a co-worker to explain a little. It's disconcerting at first to see fiction presented in such a non-fictional manner.
I gave my Dad the Philip K. Dick collection for Christmas this year, and promptly borrowed it to read for myself. Good stuff. The book design is nice too - peek under the dust jacket.
Mea culpa too on The Bhagavad Gita - Petruchio ran the list by me and we both missed it (although I had earlier made him take the Bible off the fiction list!)
(For the record, I voted for Gravity's Rainbow.)
