Many things

Randy wote: Having researched this somewhat a year ago, I'm going to (partly/mostly) disagree. DjVu files are only slightly smaller if they use lossless compression. By default, DjVu uses lossy compression, which is significantly smaller. But for archival purposes, I *much* prefer the lossless coding. Should I decide to OCR the documents at a later date, having the lossless bits is much better. The lossy encoding is designed to throw away stuff that has minimal effect on the human visual system when not under close scrutiny, but that isn't necessarily stuff that won't help an OCR program. Also, G4 coding is a much better known standard. If fifty years from now someone has to build their own drive to read an ancient CD, and discovers that it's full of compressed images, I think they've got a much better chance of being able to decode G4 images since the format is well-documented and well-known. However, if someone else went to the trouble of archiving a bunch of old computer docs in DjVu, I'd still thank them for doing so, as it is quite obviously much better to have the docs in DjVu format that to not have them at all.
