Last year I used a program to download an online book
http://www3.shropshire-cc.gov.uk/etexts/E000112.htm Precious Bane and I used Calibre for converting it to mobi. Now I'm studying the Calibre Manual in greater detail and wanting to do the same.
The problem is, i have totally forgotten which program I used to get it off the net, so I'd much appreciate a memory jog, or a similar way of getting a book off the net to read on pc or ebook reader.
