Its put out every year by the Newcomers Network. They also put out a book every year called the Newcomers Guide. Yes its used all over. For some people its like their Bible- They read it cover to cover ; )
In all seriousness, it has all the info you will ever need t live here and its very accurate and very well put together. I pull my copy out at least once or twice every week. And im already living here over a year.
