Junior Library Guild DigitalJLG Digital offers streams for Elementary, Middle School, and High School readers. Each stream delivers more than 150 revolving titles each year, with each title remaining in the stream for an average of 30-90 days. An unlimited number of readers can access any book at the same time and as many times as they choose while it's live in the stream. At the end of each book’s trial period, you can see which titles are most popular with your students BEFORE you purchase and permanently add them to your print or digital collection.
