Ministry of Type is a one-man catalog of type, lettering and calligraphy catalogued by Aegir Hallmundur. The site is elegantly displayed and easily searchable. It is I Love Typography from the other side of the pond.
While we're on the subject, Johno, the esteemed creator and keeper of iLT also keeps a running blog of inspiring images, juststuffifind.com. Oh, and the collaborative and searchable site We Love Typography. Worth a look – both of them. I promise.
