Friends gave me a set of "The Complete National Geographic Magazine on CD". It covers from the first issue in 1888 up to the end of the 1990s.
The NGS just scanned all the pages as JPG and let it go at that. The resolution is poor enough that the text is not too easy to read. About three or four CDs cover a decade of the magazine including all the adverts.
A page of text occupies about 56 kilobytes. A double-page color image takes about 150 kilobytes. I would recommend against such severe compression.
