To expand on Steve's advice...
Seek out these books on your visit to the bookstore.
Mark Wilson's Complete Course in Magic- The new edition is an over-sized softbound. Black in color.
Magic for Dummies- By David Pogue. Yellow and Black.
Both of these books are perhaps the best easily found books to get started in magic. They will most likely be located in the "Games / Puzzles" section of your local bookstore. They are also available for a good price online from Amazon.com.
For the time being, here is a nice online card trick (a variation of an old classic) for the beginner to magic you might enjoy learning and performing. http://waterloomagic.netfirms.com/BMJframe.html
Best of luck with your Magical endeavors.
