I strongly suggest getting 'Magic For Dummies' and 'The Complete Idiots Guide to magic' Both are fantastic books on general magic with many great, fun, tricks. But there's lots of card stuff in both that you can do right away and practice your performing
skills. Both books can be purchased at most booksellers including Amazon.
After that a good buy would be 'Royal Road to Card Magic' by Jean Hugard and Fred Braue. This has sleights and tricks using those sleights. It's a good idea to practice learning from books if it's not a skill that you already have. Again, this book is cheap and on Amazon and if you read it well, you will find great magic.
To see some of the moves in action, Richard Kaufman's dvd "Basic Card Technique' is a good buy. Can be purchased here: http://www.mymagic.com/kaufman.htm
There is a multi-volume sets that demonstrate moves by Daryl but this is the best single volume for the money.
This will all take you awhile to digest but after that you will probably want to get the CARD COLLEGE books. But after reading Royal Road and watching the Kaufman dvd you should be able to tackle a pretty broad range of material including people like Peter Duffie, Aldo Colombini, Al Leech.
And that's just for cards!
