Through our nationwide InterLibraryLoan service we can scour the country for almost any obscure item you want. There is a $5 postal charge if the item is shipped through US mail, UPS or FedEx. Call or stop by the library so we can get the search underway. (Please bring as much information as you have: title, author, publisher, copyright…)
