Kudos from Bruce
“We love Atriuum just like it is!

Everything is working great, and our patrons love our OPAC. We take full advantage of all the backgrounds to keep everything ‘fresh’. I am not sure what more I could say to Bruce? We are very happy with it, as is. Let me know if there is something more, but we are very happy.” Lisa BellDirector — Sunfield District Library
Kudos from Cassidy
“Cassidy Anderson supported me through trying to change the barcodes… She is incredible and so knowledgeable! I am a new librarian at a school and there were approximately 100 books that haven’t been processed yet or shelved. I wanted to get them in the kiddos hands and Cassidy walked me through and helped me tremendously… She’s a valuable and knowledgeable employee and I was blessed to have her to help me. Thank you!” Amber HeathLibrarian — North Middle School
Kudos from Nathaniel

Real feedback from libraries who rely on Atriuum every day.

Book Systems, I just wanted to thank you for all that you have done for the FBA Media Library. It has made it one of the best loved libraries around. Your support team has been fabulous, answering any and all questions (even the crazy ones) promptly, courteously, full of knowledge not only about the software but how libraries should work, and always with that little extra something. I always felt as though they were an extension of my staff.
