A 45 second update on how Evernote is helping me breeze through volumes of correspondence.
On my laptop, Evernote is running. I create a folder for each box of materials I examine. In that folder I create a folder for each archival folder within the box. In that folder I create a note where I type, of course, my notes.
Simultaneously on my tablet, I use Evernote to take photo notes. If I want a copy of a letter or a detail, I shot the photo and it goes to the corresponding folder for the box and archival folder.
Both laptop and tablet are syncing that material over the internet as I work.
Super fast, keeps documents organized, and perhaps best of all, no mass of scans and photocopies to deal with later.
