A digital-works clearinghouse comprises a database, which stores information relating to digital-works retailers and digital-works providers. Furthermore, the digital-works clearinghouse comprises a server configured to coordinate digital-works transactions, such that, when a digital-work request message is received, the server causes transmission of a digital work, which is not associated with a request-generating digital-works retailer, to a user without the user leaving a user presentation by the request-generating digital-works retailer. |
