The Smith-Kettlewell Technical File was a file published between 1980 and 1998, for blind and visually-impaired electronics professionals and enthusiasts.
It contains a great amount of electronic data.
Of course some of it is out-of-date, and I am not sure whether the links to all suppliers of components have been removed or updated where they are stale.
But it still contains a great deal of useful data, and technical articles. Including about blind soldering.
