From the BBC News website:
Bletchley Park WWII archive to go online
The downside is they think it'll take three years to do the first phase.
Some more detail
here of what we can look forward to from the Bletchley Park scanning project. For instance:
"… thousands of card indexes on different subject matter … In addition … there are log-books containing the original typescript of intercepted German messages … three fairly large rooms stacked floor-to-ceiling and wall-to-wall [of books and cards]."
And this from the latest
Bletchley Park newsletter.
