Thanks for the advice, guys - I was wondering how good scans of a top-down open-spread magazine scanner like those CZUR machines could be, and I admit that HUGE part of the appeal of using something like that would be, yeah, that I wouldn't have to destroy these magazines/yearbooks AND I'd be able to scan them relatively quickly just by flipping the pages and pressing a button (I'm an artist who grew up using flatbed scanners to scan artwork and books/magazines for reference and I swore I'd never go back to that way of laboriously digitizing piles of paper unless my life depended on it.)
Also, I had no idea that Retromags held itself in such high regards (at least in comparison to archive.org) - not that I'm complaining, I'm glad that someone is taking this as seriously as humanly possible and is working to archive stuff like this at a professional level.
That said, is there a FAQ anywhere of what Retromag's standards are in regards to file formats, file sizes, acceptable resolutions, etc.? I'm not sure I can live up to the expectations here, but I'd like to at least have a firm grasp of how high the bar is before considering whether or not I can jump it.
