Proper citation of any materials taken from this site would be appreciated, and it is recommended that revision codes be retained, since these materials are regularly updated and it's good to recognize outdated items in circulation. Top and bottom menus provide navigation -- including sitemap, updates, and Google search -- along with access to email, a blog, and a set of hyperlinks. A banner at the bottom of the page promotes a particular document each month, along with access to a comment board and a donations page. All sensible feedback is welcome.
