Greatest library software
January 13, 2017
“I have a vast library and the thought of getting software to automate it had me horrified. This software was well priced and the customer service has been tremendous. They have gone the extra mile to help a non-computer guy like me to make sure I was able to get up and running. When I have had trouble because of my ineptitude the customer service has gotten back up and running again. I will never stop using this software.” — Ron Clites
