The library is attempting to keep up with the times by having on-line check out of their books. These eliminates the need to physically go to the actual library. The only down side is you only get the on line version of the book for 14 days. So if your job and other elements prevents you from finishing the book during that time, the book "lease" expires and you have to go to the back of the line to borrow the book again! I wish they allowed 21 days.
Also, if you do go to the actual building, the Internet service is slow.
