Paper manufacturer NewPage provides the Ed Lives Here site, a useful resource with information about paper, printing, and design. One of the features of this site is a glossary of printing terms. The glossary provides categorized sub-glossaries, as well as the typical a-z index of terms, and a search input. Browsing through the glossary is facilitated by the A-Z links, which use a fish eye lens to bring focus to a section of the list.
