Introduction
A tag is a user-defined keyword associated with a title. In the ISFDB a tag forms a relationship between a title, a user, and the keyword. Marking a title with a particular tag makes it easy to find other titles that also fall into that category. While tags should generally be descriptive ("space opera", "time travel", "alien invasion", etc), they can also be used to construct personal lists ("read list", "verification list", etc). There is no official namespace for tags, they can be whatever a user wishes them to be; however, reusing existing tags ("time travel", instead of "time-travel") minimizes the search path for other users.

Tools
There are four kinds of tools that show tag-related information:
 * All tags (by all users) associated with a title are displayed in the title.cgi application.
 * When a tag is clicked from title.cgi, it takes the user to tag.cgi, which shows all the books tagged with that keyword. Displayed at the top of the page is the list of users who utilized that particular tag.
 * When a user is clicked from tag.cgi, it takes the user to usertag.cgi, which shows all the tags that particular user has entered. This page can also be displayed by clicking on "My Tags" in the navigation bar.
 * When a tag is clicked from usertag.cgi, it takes the user to usertitles.cgi, which shows all the books that particular user has tagged with that label.

Editing Tags
Adding a tag to a title is straightforward. When viewing a title, click on the "Add Tags" link. Your current tags for this title will be displayed in the input fields. If this is your first edit of this title, there will be a single box labeled "Tag1". You may add additional field lines by pressing the "Add Tag" button.

For reference, the current tags for this title are shown at the top of the page. The second section shows all of the current tags in the system, which should help you pick consistent tags.
