dustbury.com: None of their business

In doubt that patron's read your online policies? Well, dustbury is reading and evaluating Metropolitan's policies.
dustbury.com: None of their business: "Beginning immediately, applications for library cards will not ask for the patron's Social Security Number. (This is in keeping with state policy, which has barred the SSN from driver's licenses.) The eight-digit card number will no longer be printed on the checkout receipt, and transaction records will be deleted once the transaction is completed (material returned and any fines paid). And the library's customer list is not available for sale or rent.
I'm wondering if the deletion of transaction records isn't intended as a foil for the USA Patriot Act, Section 215 of which is supposed to override state confidentiality rules for libraries."
