You could potentially store the disk catalogue (directory listing) in the database too, outside of the disk images. That might be handy for searching / comparing [1], although it's not vital - and it would require you to have tools to read the directory information from the imagedisk / catweasel archive formats at the point of inserting the images into the database. [1] less of an issue for commercial software, but it's useful if you have a lot of 'working' disks containing homebrew software and the like. Some other things you might want to capture: When you got each disk Who you got it from Some sort of 'batch' number The latter can tie together disks that came in the same pile / haul / box and can be useful if you find something interesting on one disk and want to investigate others from the same batch to see what they contain. Actually, I'd have a think about what sort of 'media type' fields would be useful, such that you can have an archive which copes with other disk sizes rather than just 8" - that way other people can add media once the archive goes online. cheers Jules
