<a target="_blank" href=...> opens a new, unnamed window. <a target="example" href=...> opens a new window named "example", provided that a window or frame by that name does not already exist. Note that the TARGET attribute is not part of HTML 4 Strict. In HTML 4 Strict, new windows can be created only with JavaScript. links that open new windows can be annoying to your readers if there is not a good reason for them.
