The decision tree exists as an interactive web site and PDF document. It took me a bit to see that I need to click on my decisions -- you can't just scroll! Although we assume that materials that we digitize should be preserved, going through this decision tree would yield clearer thoughts on the topic.
Clearly defined selection policies will enable cost savings in terms of time taken to establish whether or not to select and also potential costs further down the track of needing to re-assess digital resources which are either in danger of becoming or are no longer accessible.
This Decision Tree may be used as a tool to construct or test such a policy for your organisation. The decision process represented in the tree should be addressed by your policy for selection of digital materials for the long-term.
