This second edition extends the approach adopted by its predecessor by widening its coverage of issues even further. In particular, the changes wrought on traditional collection management practices by the advent of a range of information and communications technologies are addressed. In addition to a full revision, the second edition contains two new chapters by Ross Todd and Daniel Callison that relate knowledge management to managing information collections. A third new chapter by Donna Shannon discusses some of the dilemmas that affect collection management practice in a digital age.
