Hello,
 
At the University of Colorado-Colorado Springs we are currently in the
process of implementing online access to our collections through our
library OPAC. We would like to prepare for possible future implementation of
a more advanced archival management software by creating our MARC21 records
to be compatible with EAD.If we plan our MARC21 fields to correspond with
EAD fields will this sufficiently prepare us for any future time that we may
need to export our records from the OPAC into a different archival
management software that utilizes EAD? Has anyone else out there done this?
Thanks for any help you can offer.  
Sincerely, Caroline
