Downloading Google Help files

Google has got a superb Help which caters to almost all the needs of a user. But what if we want to download them and make them available offline? Append ?fulldump=1 to the address of a Google help center. This doesn't work for all Google services, but here's a list of addresses that dump all the information from a help center (note that the pages are very large and are frequently updated):
