Scott:

Thanks for your thoughts.  We will certainly consider them as we develop
an action plan for this material.

Ed,

I would strongly second all the points that Richard brought up.

I would also point out that it is critical to include relevant  
metadata at the time the source materials are digitized.

In general, most archives are moving their collection resources to an  
online environment, either internet or intranet based. Without a  
cohesive system of metadata and keyword coding, it is impossible to  
move assets into an online system.

I would strongly urge that you review the requirements that you will  
have for access before embarking on a large scale digitizing program.  
It is relatively easy to deal with the metadata issues during  
ingest-much more difficult to go back and re-visit it later.
