Where can I find a list over third party unit/component name prefixes

Question

Most third party component vendors uses a spesific prefix for their own unit names and component names.

Can I find any overview over these prefixes anywhere?

Eg

gtUnitname = Gnostice
frxUnitname = FastReport
cxUnitName = Developer Express

Two reasons
1) Need to find the vendor of a unit
2) Want to use a unique prefix in own components

Answer 1

Once upon a time, there was Delphi Prefix Registry but now it's sadly defunct. (And, anyway, it never was much of a reference - most of developers just used their initials and didn't care much about the rest of the world.)
