I've dashed off some more stuff for saveaussiemusic.org. They're not cirectly relevant to Commons - almost nothing I'm talking about is likely to be freely licensable, let alone public domain - and the copyright issues surrounding this are a minefield, which is why we're still seeking libraries to partner with - but I would be most grateful to have clueful people look over them and see if there's anything wrong or that I've missed in a technical sense. The use case is people with a collection of interesting cultural materials (records, books, magazines, flyers, photos) who don't want to donate the physical objects to a library but would be quite pleased to donate digitised copies. So they'd probably be doing this stuff themselves at home. http://wiki.saveaussiemusic.org/wiki/Digitising_audio http://wiki.saveaussiemusic.org/wiki/Image_scanning http://wiki.saveaussiemusic.org/wiki/Negative_scanning I am particularly interested in anyone who knows anything about preserving reel-to-reel tapes. Does anyone have handy guides to extreme tape preservation techniques? (I've also asked someone at Internet Archive, of course, who are directly acquainted with all of these areas.) - d.
