Creating a inventory of computer hardware

Hello,

I am beginning an inventory of our library's computer hardware collection
from the last six years. Has anyone worked on a similar project?  If so,
would you be willing to share your experience and advice?

Our extant computer inventory lists are in Excel, although we have two
Access databases also.  I think Access is the better program for an
inventory project.  I will need to merge these lists, and decide what fields
of information to retain, and what to discard.  If you need further
information, please let me know.

I appreciate your help!

Sincerely,

Maria Vagianos
