Identifying manufacturer logos on components

I've found this link at Google: http://www.advanced-tech.com/ic_logos/ic_logos.htm

http://www.westfloridacomponents.com/manufacturer-logos.html (dead link) featured logos for around 400 manufacturers, alphabetically by company.

The last capture I could find of it is https://web.archive.org/web/20170817083634/https://www.westfloridacomponents.com/manufacturer-logos.html

The PDF version linked from that page is a printout of the same page from 2009-05-28.

The IC Photos site is also a useful tool for this type of effort.
