Some account information resulting from transactions you complete in a session are not updated until you logout and login again.
For example, if you place a hold on an item that is 'Available' Bibliocommons debits your number of free holds in its' display. This information is corrected after you logout and login again. (Note: our main database has the correct data; Bibliocommons refreshes its' display everytime you login).
The same is also true for fines that are calculated when you renew an overdue item. Bibliocommons does not display the new fines total until you refresh your session by logging out and in again.
Also please note that the count of holds on a title may not be accurate as this information is updated hourly.
