Marketplace system capable of using purchase history data to generate listing request messages

An electronic marketplace system provides various features for assisting users in listing products for sale, locating the listings for a product, and performing related actions. A user wishing to sell a product can browse to an existing description of the product in an electronic catalog and then select an option to create a corresponding listing. If the user previously purchased the product via the system, the user may alternatively select the product from a personal purchase history. The system may also proactively send product-specific listing requests to those who have purchased or otherwise indicated ownership of specific products.
