This tutorial from Cornell University touches on just about every issue you will encounter in implementing a digital preservation project. The explanations of image quality issues including file size, resolution, color, and file type are the clearest and most thorough I have ever encountered even after working with images daily during my years in advertising.
The section on metadata is easy to understand and integrates tools like this lovely metadata table. The entire tutorial features periodic questions to test your understanding of complex concepts as well as resources for additional reading.
The management section discusses pros and cons of outsourcing versus in house management of digital projects. Finally, the continuing education resources are phenomenal. I could spend the rest of my winter break just delving into these resources if I didn’t have to work on job applications instead.
Finally, here is an example of a real live project based on these tenets. I worked on this at The Seattle Public Library this fall and the planning really does take into consideration all the points raised by the Cornell tutorial.
