From the announcement:
The Papers of the War Department team is happy to announce that we’re back online!
The last time you heard from us, we were putting transcriptions on hold to start a total redesign of the Papers of the War Department website with the support of a grant from the American Council of Learned Societies. This included migrating nearly 200 gigabytes of Papers of the War Department items, metadata, and image files into Omeka S, which now powers the website with a fully redesigned look and feel. We’ve also released an updated beta version of the Scripto plugin, which is facilitating transcription, with updated functionality for an easier transcription process.
