	In September, while preparing the final boxes for digitization, Amanda discovered a large folder labeled “Miscellaneous Documents” that was not on the EAD finding aid. She brought it to Donnelly, who analyzed the contents and determined their correct locations. We decided that since the destination folders had already been digitized, these items would be added to the end of the list, regardless of their correct position in the folder. To reorder the existing digitized material and rename all the other files in each folder would have been counterproductive.

One is a thumbnail, and one is the full-size master image. Unfortunately, Image Magick by default creates a jpeg from both tiffs.
