When you have time to wait a week or so for some of your books, use WorldCat to extend your search to libraries all over the country. We can even get scans of parts of books from libraries overseas.
From the libraries' homepage, select the tab Books and More, check the circle for WorldCat in the blue box, then the button WorldCat.org.
Enter search terms for keyword searching. Since you have seen records in CBBcat with subject headings of the form: author Criticism and Interpretation, use these terms initially to begin your search for criticism of Poe or Borges, or any other writer. Look at the panel on the left to see what parameters might be useful in limiting your results. Choosing Print Books, for instance, means you won't waste time looking at eBooks you will not be able to borrow. Changing the sort from the default Relevance to Date Newest First is also often helpful.
Select a book by clicking on the title. In the record for the book, click the button Request through ILLiad@Colby. Sign into the ILLiad system with your Colby username and password. The request form should fill in automatically - just click Submit at the bottom.
When something you search for doesn't come up in CBBcat, try NExpress, catalog for a consortium of academic libraries in the Northeast. Books you request from these schools will come quickly.
When you select a record in the NExpress catalog, find the button to Request this Item in the center of the record.
You will be asked what school you are affiliated with -
then for your name and the barcode on the back of your Colby ID. Type only the numerals, beginning with 25031, not the letters A and B. Books will be delivered to the front desk at Miller and you will be alerted by email.
