A new bibliography cataloguing the various editions of Harry Potter publications will help readers identify which edition of the books they own. The collection will also reveal secrets of JK Rowling’s edits, reports the Guardian. The 544-page book took Sotheby’s director Philip Errington five years to compile and includes such facts as alternative titles like Harry Potter and the Death Eaters, Harry Potter and the Fire Goblet and Harry Potter and the Three Champion.
