At least to an academic, this digital collection of “The John McCoy Family Papers” at the Dartmouth College Library is lovely. View the documents and letters from this page: http://collections.dartmouth.edu/teitexts/jmccoy/index.html
Here’s a nice example of what I find so inviting in the display. The transcription on the left is clear and easy to read, without too many interruptions except where words are illegible. The actual letter image is available on the right in a nice viewer that does not allow readers to copy or download the document, to prevent distribution. I don’t think I’ll ever have the skills or resources to do something like that (you never know), but this would be a nice format in which to display my letters once transcribed. I’ve heard (I have connections) that the collection will eventually offer a toggle to the full TEI (Text Encoding Initiative) markup, something I’d like to learn in my coding adventures.
