Often you will want to locate a specific book in the catalog by its title.
Just as with author names, no capitalization or punctuation is required.
The title search will only work if you have the correct title! So if in doubt, or if you get no results, try a different type of search: an author search if you know the author's last name, or a "Title Keyword" search if you know some of the words in the title, but aren't sure of the whole thing.
And as always, feel free to ask a librarian for help at any time!
