How to add fonts?

[M Grosse]

My newly installed version of Excel 2000 (from Office
2000) is missing some fonts that for some reason appear in
Excel 2000 on the computers I'm networked with.
What's stranger is that I used the backup manufacturer's
CD to install Office on my machine.

In any case, I really need 3 specific fonts for my Excel
program: AGaramond, Trajan, and Copperplate 33BC

Does anyone know how I can obtain those? Either free or by
purchase, either way (free, obviously, preferred)

Thanks for any assistance
