Most ebook error messages happen because only one person can view an ebook at a time. If someone else is already using the ebook, there is often an error message that says, "Sorry, this book is in use." If you see this error message, wait and then try accessing the book again in about 30 minutes. 

If you continue to have difficulty accessing an ebook after several hours or if the error message says something different than "this book is in use," please contact a librarian for assistance. Librarians can be contacted by: 

1. Chat. Use the green chat button on the library website. 
2. Email. If chat is unavailable, email a librarian at: http://ask.colum.edu/q.php
