Since these mags and books are all out of print but of interest to many especially in groups like this; it is a shame no one just scans them into a jpeg file and posts them somewhere for posterity.
Ever scanned magazines? It's a time consuming and never-ending job.
Moreover, as pc's become more powerful and monitors go to higher and higher resolutions, the scans of today become tiny little rinky-dink images on pc's. I must have scanned thousands of images back in the late 90's and when I open them now they are just a step above thumbnail size.
And then when you now scan in hi-res, say at 600 dpi, each scan takes longer and longer to finish as compared to previous high-end dpi resolutions - 300 dpi. And many magazines are larger than most affordable scanners. Which means stitching parts of pages together ... also time-consuming as can be. Figure at the very least 1 min per scan, so when you get magazines of some 50 pages or so, that means an hour of scanning time.
Scanning complete magazine collections is a big job. Something for institutions to do, not for private enthusiasts who get little compensation for their efforts except maybe a thank you, if even that.
But of course you're right about preserving old magazines for posterity. Though remember what happened to microfilm archives. They were all the rage in the 70's/80's, libraries threw away their physical magazines and newspapers after microfilming them and now we have them all on an outdated media, sort of like the old wire spool recording for sound back in the 30's. Meaning they are all but useless unless you have the right, hard to obtain equipment.
Technology is a harsh mistress.
