From Ian's tedious labours scanning the documents, I have taken all the files and reviewed them. There seem to be some issues missing, a few duplicates, a few incorrectly named, scanned 2-pages to a page and comprise images only. So I have taken the files and split them into separate pages, scanned them for OCR (optical character recognition), compressed each file, renamed them, added some files that were missing (there are still a few issues missing which I will add when I get my chess library out of storage at some stage in the future) and then uploaded a complete new set. What all this means is that the files are more complete, they are correctly named, open more quickly and can be searched for particular words.
