This is a set category. It should only contain pages that are Types of auction or lists of Types of auction, as well as subcategories containing those things (themselves set categories). Topics about Types of auction in general should be placed in relevant topic categories.

Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.

These are the articles about different rule sets for auctions.
