When users request items with multiple volumes in the resource sharing form (NERS Enhancement - Request ID #4856), they can select a specific volume from the pull down list, also freely enter the volume information in the box. Errors of manual input may lead to in inefficient or failure of handling the requests, e.g. user input “1” in the text box instead of selecting “v.1” from the list, the request can be created successfully, but the description cannot be shown in “Borrowing Requests” of Borrowing Library or “Pick from the shelf” of Lending Library, the libraries need to spend extra time to check with each other and the user to confirm which volume was requested. It is advisable to block the free text input function and force user to select volume from a pull down list.
