Font in Logo, created by software company Azwedo, is a new, user-contributed archive that lists the typeface used in logos. Around 200 logos have been added so far. Could be a rather useful reference site as it grows. [Edit: I admittedly did not click thoroughly enough on the site but, as many here and on Twitter have pointed out, there is a lot of very wrong information on there so I’ll rephrase the ending of my original sentence as “Could be a rather useful reference site if it were less wrong about so many things”.] Visit link
