Here’s a review of Essential Classification by Vanda Broughton, a core Library Studies textbook and very easy read. It’s a sound introduction to classification – very practical and really aimed at trainee librarians, but included enough background and theory to keep me interested, including some pointers to the biases in the big classification systems. I was also intrigued by the assertion that people find it easier to remember numbers, so numerical shelfmarks are generally more popular than those based on letters. I always thought it was easier to remember letters, because you can make them into little phrases, but perhaps that’s just me!
