Follow up on WP Verifiability Hi I see from your edit history that you ve just been on Wikipedia for a couple weeks Just to follow up on the punk rock matter basically the more established an article is the more you need to be prepared to verify your information and cite good sources for things you re interested in adding the existence of a record itself is not generally considered a good source unless it s got detailed liner notes that can be cited For new articles or ones still at any early stage of development the practice is a little looser and any information that steers the article in the right direction tends to be seen as helpful The punk rock article happens to be one of the most established articles on Wikipediathat little star on the top upper right of the article tells you it s a Featured Article one of our best You can look at the whole list of Featured Articles hereWP FAto get a sense of how they look and specifically the kind of citations they have Anything you add to a Featured Article or what s been designated a Good Article just a tier below will generally have to pass a pretty high standard of verifiability I hope this help clears up what happened in this case the existing sentence s focus on 1977 is also significant of course I hope you enjoy editing here All the best Dan
