What is this? It's a tag!

Tags are just another way for people to name or categorize information on the internet -- they can help you find and compare items which are similar or related. Adding tags is a great way to share your knowledge about the content of a book, CD, or DVD. And, you can add as many tags as you want! For example, if you've just read a book about gardening in Canada, you might tag it as belonging in the following categories: Canada, Gardens, Flowers, Non-Fiction, Horticulture.
