Toward a Content Philosophy

• Principles of academic freedom and learner
  discovery
• Acessioning at the collection level, for
  scalability
• Accessioning priorities set with stakeholder
  representatives, with goals of breadth, depth,
  educational value
• De-accessioning (rare) under guidelines set by a
  board of experts in library principles
• Educational value, relative to age-specific and
  other contexts, to be manifest in capabilities
  for annotation and selective filtering, rather
  than an accession threshhold
