You can give books on the Progressive Book Club site a "tag", which is like a keyword or category label. Tags help you find books which have something in common. Tags are usually (but do not have to be) single words, and should be descriptive and make sense to you.

A "tag cloud" of all your tags will appear at the bottom of your MyPBC profile, if you choose to create one. A tag cloud is a visual depiction of your tags in which the more important tags (i.e. those with more books are associated with them), appear larger. Tags are hyperlinks that lead to a collection of associated books.

A tag cloud aggregating the tags of ALL PBC members and community members appears at the bottom of all book browsing pages.
