First, find the book you need in NExpress. http://nexpress.iii.com/
You can also get to NExpress from the Colby Libraries home page by selecting the 2nd tab down in the menu to the left of the big blue box. The orange arrow bar should now read BOOKS AND MORE. Select NEXpress from the catalog choices that are now displayed in the big blue box. (Or get to NExpress from within CBBCat by clicking on the NExpress icon in your CBBCat search results.)
Enter the Title or Author or other publication information as prompted.
Select the book you want from the results list.
Click on the NExpress library holdings ("x NExpress libraries have this item") to check on availability. If the book is available in the system, click on "Request This Item". (You will not be able to request a book if it is listed as available at Colby.)
IMPORTANT: when asked "With which institution are you affiliated?" don't forget to select "Colby College" otherwise your request cannot be processed.
Now enter your name and the barcode number from your Colby ID card. Submit your request.
