The book I need is checked out...

Sometimes a book you want for your research is already checked out by another student. When an item is checked out, you can usually request a copy from another library for free.  First, you will need to sign in to OneSearch.  Then, you will see a request link for CSU+ if the item is available at another CSU library.  If the item is not available at another CSU, you will see a link for Interlibrary Loan (ILL)
