It would be really interesting to see a GLAM initiative which used Wikisource as a transcription interface.

The best GLAM example of using Wikisource so far is Dominic's work with NARA in the USA - see http://en.wikisource.org/wiki/Wikisource:WikiProject_NARA/Completed. I used the example of http://en.wikisource.org/wiki/Objections_to_Woman_Suffrage_Answered at the all staff presentation at the British Library as an example where a formal archive's catalogue links directly back to Wikisource as an 'official' transcription.
I am hoping that NAS can use a similar approach.
