This is a common question on these forums. People see a font they like, and try to locate a close match or identical font. While searching for info on Bitstream fonts I came across this service click here which will find the closest matching Bitstream font. Just create a suitable bitmap from a scan or screen grab of the font you are searching for.
Bitstream collections are widely used. WordPerfect and Micrografx users will already have a good number of them.
