Those who have been waiting impatiently for the first stable release of the Text Image Linking Environment (TILE) toolkit need wait no longer: the full program can be downloaded from: <http://mith.umd.edu/tile/>. From that site:
The Text-Image Linking Environment (TILE) is a web-based tool for creating and editing image-based electronic editions and digital archives of humanities texts.
TILE features tools for importing and exporting transcript lines and images of text, an image markup tool, a semi-automated line recognizer that tags regions of text within an image, and plugin architecture to extend the functionality of the software.
I haven’t tried TILE out for myself yet, but I’m looking forward to doing so.
