Titan - Obtaining a copy of
Watchmen shouldn't be too hard....last time I checked, the Trade Paperback Format (all the issues are collected into one nice little package with a few extras) is widely available at bookstores.
However, if you want a copy on discount (since I think that the original is around $19.95.....check out
www.amazon.com for a good price. That's where I tend to get my TPB's in good fashion.
The Discworld Series is available in all bookstores, except they only have them in paperback form. If you're like me, I enjoy having a hardback book. I don't like the paperback format because it's usually smaller, and more of an annoyance to read, because you have to keep on constantly bending the binding, and when you're done with the book, it looks like shit.
You can find his most recent books in hardback still, and
Theif of Time is one of his most recent ones. Others, like
The Truth,
The Fifth Elephant, and....
Night Watch should also be available in that format. There's a Science Fiction Book Club that has incredible discounts on SF classics, and that's where I get older Discworld books for really really cheap prices in hardback format.
PM me if you want more info....
