You can set the checkout limit, between 1 and 99 titles, using the administrator tools.
First, log into your MackinVIA Administrator account (https://www.mackinvia.com/Admin) with your Mackin.com email address and password.
Choose Settings > Checkouts/Requests (make sure you select the correct VIA if there is more than one account).
Make sure the button next to the Checkouts label reads Enabled. (If the button reads Disabled, click to enable.) Enter the maximum number of eResources you want students to check out at one time in the Limit box (you can choose up to 99 titles).
Click Save Changes when you’re finished.
