I told a friend a while ago that i only buy books that i have read before and liked.
Because, i will only keep books that have some "re-reading" value.
Hence, you will seldom see me buying new book off the shelf unless it comes with strong recommandations.
In the meantime, i will check things out in the library or borrow from friends.
Or read them in the bookstore.
If i liked it, i will buy it.
Guess i am a re-read-buyer sorta person.
