GRRL libraries have many Large Print books for the convenience of readers who prefer larger type. Many new books are published in regular and Large Print at the same time.
Catalog searching techniques will allow you to specify large print as a format. For instance, in the Basic search you can type Large Print Grisham to find a list of Large Print by John Grisham.
Books new to GRRL can be found in the New, Best & Fun list for Large Print.
