How quickly will new titles appear in SimplyE?
Simplistically, OverDrive scripts that update run every 15 minutes. After that, another script runs to recreate the catalog. So, for OverDrive, one would assume it takes at least an hour. Other vendor scripts may run only once per day. Short answer is: depending on a number of factors, we expect the titles ordered today will be in the library’s SimplyE catalog tomorrow.
