Marking articles for cleanup
If you don't have time to do anything more than tag an article as needing cleanup, that's fine and a very useful thing to do. (Reading and evaluating articles does indeed take a lot of time and is certainly real work.) If you do have the time to do so, it would be helpful to fix one article already on the list for every one that you add. This helps ensure that at least some fix-it work actually does get done, and helps keep the size of this collection from growing without bound.
Where to find articles that need cleaning up
All articles that have been identified as needing remedial cleanup are listed in one or more of the categories mentioned in the "Table of remedial cleanup tags" section below, or in one of the following old-style pages. Mark them for cleanup according to the process above. Please do not list new articles on these pages.
The following is a listing of useful cleanup tags. Some tags have alternate versions which are used if the applicability of the tag is disputed. That page also gives more specific instructions about where to put tags, if the top of the talk page is not the best place.
