Heads up, librarians — this may be of interest to you. My review of Wikipedia – the Missing Manual by John Broughton was published this weekend on Blogcritics. There has been some discussion among the profession about our relationship to Wikipedia, ranging from warnings against using it to calls for librarian contributions to the content. For those interested in the latter, I recommend picking up a copy of this book (your library should have one, too).
…Wikipedia has plenty of documentation on how to edit itself, and if you are willing to find your way through all of that, you may not want to read this book. I have muddle through a few Wikipedia contributions (both new pages and copy edits on existing ones) without this book, but in reading it, I frequently found myself making notes of things to look up later or tweaks I could do to make editing easier. The book does not contain anything you probably would not find on Wikipedia. Instead, it takes that information and lays it out in a workflow that is designed to take the novice user from ignorance to full-on Wikipedia-obsessed editing.
