OK. This changes the game.
Using Evernote, the new software to integrate collections of images and text across platforms, graphic facilitators now have a tool that allows for their work to be searchable.
It works, too! Once you upload, drag-n-drop or email a photo of a drawing, the software adds it to a "notebook" that is either public or private. Then, the user can do a normal word search and Evernote finds the word--even in handwritten form!
