Thanks for this. Any info on the stability of the 'paper images' taken off
digital photos and submitted as part of a report?

Hi Peter,
Further to Nick's comments I'd just like to emphasis that both the file
format and media are equally important with regard to preserving digital
images. File formats require software in order to be interpreted and often
the standard or the software to read the format will change over time (more
so with proprietary formats). Other format-related issues such as
compression (e.g. JPG files) also need to be considered when archiving
images.
With regard to the use of media such as CDs, the ADS recommends that, if
used, these are actively managed through back-up and migration processes to
avoid the data becoming unreadable either through media corruption or
software obsolescence. For more info see our Guides to Good Practice
(http://ads.ahds.ac.uk/project/goodguides/g2gp.html) or guidelines for
depositors (IV:A Ensuring Preservation
http://ads.ahds.ac.uk/project/userinfo/deposit.html#preservation).
ADS, in conjunction with FISH, is also in the process of producing more
guidelines on archiving...so watch this space!
The TASI website is also well worth a look for more info on images:

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)
