U.S. Championships

Getting started with Been There, Done That, I added U.S. Chess Champions and U.S. Chess Championships (Closed/Invitational) to my page on Chess History. I wanted to tackle British and Canadian championships at the same time, but Archive.org was offline for maintenance, so my time was limited. Their error message pointed to a related resource which I hadn't seen before -- Internet Archive Blogs -- 'A blog from the Collections Team at Archive.org'.
