I guess the former depends more on the quality of the CD-ROM and the writer used (in common with all such archives) rather than on the software/format selected.
Not quite right. If the format is no longer supported in the next release of your operating system, or by your IT Dept's changes, then the format and software used will be critical.
I am not sure of the life span of CD's but would hazard a guess that this side of things will be more of an issue (ie changing formats and software) than the physical survival of CD's.
After all 5 inch floppies still survive, and can be read, but only if you have the right hardware to read them, and then the right software for the data.
You should also contact the ADS for info/advice (though info about this may be on their website I think)
