I have the "original technical publications" A H 100 and 100/6 1953 to 1959 from Heritage Motor Centre and consider it a waste of money as a technical resource. The info is available elsewhere and the quality is as if it has been run through a fax machine. You can't zoom into any detail and you can't search for anything because the pdfs are a series of tiny black and white scans of the factory manuals.
There is a security virus it comes with which takes over your .pdf reader. When finished it closes any open documents including in web browsers and you have to find/kill the runme.exe process afterwards before opening other pdfs.
Without technical knowledge, you can't store/view files on a hard drive- the only way to view them is through the clumsy CD interface so you can't view them on a computer with no CD drive.
If you already have an owners manual, parts book(s) and workshop manual then you could scan them at low res and make your own...
