The Coleman Brothers collection contains over 400 items, which I have arranged into 33 folders contained in two boxes. The vendor supplied the materials in the following order:

Correspondence between the two Coleman Brothers

Correspondence to and from Isaac Coleman
Correspondence to and from James Coleman
Correspondence involving various other Coleman family members
Manuscripts (including James Coleman lecture notes)

Documents - legal 
Receipts, school records, miscellaneous printed materials.
Photographs of family members

Using the vendor's descriptions, I verified the contents of the folders. Some folders held too many items, so I rearranged them to sub-groupings. I am entering EAD data for each folder, including naming and labeling the folders that provide the best guidance to researchers; the number of items, dates, and description of papers within each folder. This process involving two boxes of over 400 pieces in 20+ folders is going to take a few weeks.

Although we first started with access terms (name, subject, place and genre headings) we eventually came back to them at the last run-through, after I had worked so much with the physical arrangement and description of contents of the collection, that it was much faster to assign a handful more.

 
I used LCSH and AAT (The Getty) for creating access points to the archive. All the access points in the catalog database also had to be entered into the finding aid, with the appropriate XML tags for name heading, subject heading, genre term, etc. This is how the final product displays in Orbis:
