You can log into Freegal Music Downloads using you library card number and your password. Freegal requires you to have a Prince George's County Memorial Library System card. We allow customers to register their barcodes from other County systems if they prefer to have just one card, but those cards (barcodes) cannot access this new service. Anyone registered with a library barcode from a different county has the option of getting a PGCMLS card and using that card for PGCMLS services. The terms of our contract for Freegal and the authentication process require the use of a PGCMLS barcode.
