These days, everyone creates digital content, often without thought as to keeping it around for very long.
As librarians and information scientists, however, we need to be mindful that some of this information will need to be accessible for awhile — possibly a long while! Think of research work that you (or someone else) might want to build on in the future. Or family photos that you'll want to still look at in your old age, or share with your grandchildren.
Does the professor or student you're working with want to be able to access his own research 10 years from now? If so, he will be grateful for some recommendations from YOU as to how he can safeguard his hard work!
To assist in this, I've put together a wiki page with a list of resources that I hope you will find helpful. If you have suggestions for other additions (or even deletions or changes!) please let me know. You can find the list here: http://www.lib.ua.edu/wiki/digcoll/index.php/Recommendations_for_Authors_and_Creators
