Not related, Anun Shourie had mentioned in one article, the most interesting operation of making a particular book disappear - each single copy of it - from ALL the libraries that had it. He was doing research on Ram Janma Bhumi issue, and was looking for an Urdu book written by a very reputed Ulema/Islamic scholar in 19th century. Book was called 'Hindustan Islami Ahad Mein' ('India during Islami Rule' or some similar title).
The book was considered an authority on that chapter of Indian history. Shourie mentions how each single copy of the book had been recalled by the publisher, and that every single copy available in libraries like AMU, DU etc, magically disappeared. He still found it somehow from some private collection etc, and found that the book has a chronicle of all temples that were destroyed by the Muslim rulers, not to mention with details of how Ram Janma Bhumi was destroyed.
