At Harvard we need to implement a new library hours database/tool. We have over 70 libraries and are looking for something that's easy for staff to update (~100 staff users), and has some form of API such that other sites (like the Med or Law school library sites), can access it so they don't have to update hours in multiple places. It needs to include amenities info, café hours, etc.  Preferably staff could set default hours and then override them when hours vary.
Are there any libraries doing this that are using open-source software, and like what they have? (If you have a locally built system and like what you have, I'm interested in that too).
Many thanks,
Corinna
