Strategies for re-classification

Finally, as promised, a discussion on re-classification!

We all know that classification schemes need to change on a fairly regular basis in order to keep up with our ever-expanding knowledge, and remain a relevant way of organising the world's knowledge. Whether or not your library wants to keep up with these changes is, of course, a decision for each individual library service. There are a number of strategies that can be used to make the decision whether or not to re-classify and there are lots of different ways of going about it. Some of these issues are discussed in this paper.
