Hello, Mike, Thanks for the excellent post. There are two points that I'd like to add. (1) I was quite surprised that you did not mention the IU FACET Tool as a means of helping get ones arms around this collection by breaking it down into sub-collections and assessing the risk associated with each sub-collection. http://www.dlib.indiana.edu/projects/sounddirections/facet/index.shtml (2) With a collection of 100,000 hours, I wonder how one might go about prioritizing the content. FACET permits one to prioritize based on risk, but there is a content importance factor that is also available in the system. I wonder if, in 100,000 hours if there are any duplications of ceremonies or stories. While I am a firm believer that digitizing and preserving MORE content will be looked upon favourably by our descendants (as opposed to cherry picking a few items), I also think the burden we impose on our descendants by digitizing and preserving everything just because we can is also a big issue. I don't know the answer, but I'm becoming aware of the question and its answer should perhaps inform these huge expenditures.
