Abstract: A method and system for storing, categorizing and distributing information concerning relationships between data that involves the use of tags in place of traditional, mutually-exclusive file folders by querying any number of servers for information regarding a tag, associating the tag with data on an electronic device, and suggesting other tags that might be relevant as well.

Abstract: A method and system for transferring an electronic payment between a purchaser and a merchant that includes assigning a role of a merchant account to a first account and a role of a purchaser account to a second account within a payment system, adding an item from a product catalog stored in the payment system to a purchase list, obtaining a user ID token of a purchaser from a merchant terminal, communicating identity confirmation information associated with the user ID token to the merchant terminal, and transferring funds for the purchase price total from the purchaser account to the merchant account.

Abstract: Embodiments are directed to a system that allows publishers to publish bibliographic data, reference data, and/or author notes of non-fiction materials (e.g. books, journals, etc.) on an Internet web site with a formal structure rather than in paper form. Bibliographic references and author notes are stored in a computer database, and presented to end users through web pages in such a manner that references can be displayed alongside digital images of the physical pages that they originated from, with hypertext links to digital files representing the author's original sources, as appropriate.
