I am cataloguing the non-WM contacts I made at Wikimania. Reading up on them, basically making the time I didn't have during the conference to understand who they are. The BHL had three librarians at the conference, I remember that they were very interested in a solution for getting OCR corrections back into djvu files. They mentioned Wikisource in the blog post they made about the conference. I thought the list might be interested in what they had to say.
