How much reading time can library readers log at once?
This article pertains to library clients. For school clients, check out this article.
Readers can log up to 600 minutes (10 hours), 100 books, or 1,000 pages at one time. Anything above that will give them an error message letting them know, “You cannot log that many minutes/books/pages.”

If readers truly did read more than the maximum, they can split it up into multiple reading sessions to add it to their log. Readers can log an unlimited number of reading sessions per day.
Note: Admins can exceed these limits when logging for themselves (in the reader view) and for any other reader (in the admin view).
