An eCard is a CW MARS library card that patrons who live in a town with a CW MARS member library can register for online to access electronic materials, such as ebooks, audiobooks, magazines, and databases. The eCard is for patrons who do not already have a CW MARS library card.  eCards may be upgraded to a physical library card by visiting your local library.  Apply for a CW MARS eCard and use it online today!
