There is an option in the SEARCH BY dropdown menu at the top of the Advanced Search page and on Easy Search that enables you to search by Title and Author. (Punctuation is not necessary to complete the search.)
NOTE: Please be aware that the Search Page Preferences you select on the My Profile page may cause future searches to come back with “No Results” when in fact the title is in the Mackin database (e.g. if you have your interest level set at K-2, the Harry Potter series will not come up when you search). If you can’t find the title you’re looking for, please alter your Search Page Preferences to be less specific and see if the title is retrieved.
