Sonoma County Library invites customers to self-register online for a library e-card anywhere they have Internet access. These e-cards expire after 120 days and can be used to immediately place items on hold, stream movies and music, download e-books, and e-audiobooks, as well as access digital content that Sonoma County Library has to offer. E-cards have a special barcode with a unique six digit code followed by a hyphen and a two or three digit number (e.g. 000000-00).
