Usually a user is Barred when the address, phone number, or email address on his or her record is not correct. (Occasionally this occurs when a spam filter blocks email messages from our catalog. If you use a spam filter, please make sure to add email@example.com to your safe list.) Barred users are prevented from checking out any items, placing holds, or using our online ebooks collection. Other services may also be impacted. You may contact the Library Circulation Desk to update your information and restore access your account.
