Certainly in keeping the book up to date, it would be very helpful. The House of Representatives Practice manual is now in its seventh edition, and it came out originally about 20 years ago.
Odgers', which is for the Senate of the Australian Commonwealth Parliament, is in its 14th or 15th edition. Erskine May, which has been published since 1844, is soon to have its 25th edition.
What will happen, though, with the next edition of the House of Commons Procedure and Practice is, again, that in a more proactive attempt to be of help, there will be a section in the book on what members need to know under each chapter, because when I was reading and studying the book—and I don't mean this as a criticism; please be clear about that—I found out that in the chapter on oral questions—and I've become notorious for this because I just don't let it go—the fact that you're limited to 35 seconds is buried in footnote 41.
