I am always surprised when I hear our patrons say, “I had no idea you had eBooks!” It seems like a natural fit for libraries to expand their collections to the digital realm by including eBooks. However, it’s also understandable that they’re an invisible collection, which could make them easy to miss.

If you’ve ever checked out an eBook from the Delaware County District Library, it’s likely that it either came from the Ohio Digital Library or Axis 360 collections. The main difference between these two collections is who they serve. The Ohio Digital Library is a consortium of many Ohio public libraries who share materials to patrons all over the state.

Axis 360, on the other hand, is a separate collection of eBooks purchased by DCDL to be used exclusively by our patrons. This is a great resource for DCDL patrons to get bestsellers more quickly into their hands – or tablets.

Now a new Axis 360 app makes the collection even easier to use. Simply download the app to your mobile device or computer, locate Delaware County District Library and sign in with your library card number. If you’re a new user, you’ll create a four-digit PIN and use that to continue the login process. Then use the “My Library,” “Browse” and “Search” functions to locate an eBook. Simply tap the “Checkout” button to borrow an eBook, which will download directly to the app. Your checked-out titles appear in the “My Stuff” tab. While you’re searching the app for your favorite titles, look for some of these, new this month to our collection.

• “Andy and Don” by Daniel De Visé. Featuring extensive unpublished interviews with those closest to both men, a revealing biography celebrates the powerful real-life friendship between co-stars Don Knotts and Andy Griffith behind the scenes of “The Andy Griffith Show.”

A final novel by the late Pulitzer Prize-winning author of “The Mambo Kings Play Songs of Love” is inspired by the friendship between 19th-century journalist-explorer Henry Stanley and Mark Twain throughout a journey to Cuba in search of Stanley’s father.
