When we find it in the catalog and go to place a request, we get a message saying that we need to select and request an individual copy.
To do this, scroll down the list and select the issue that you're after. Look for the hand/book icon and click on that to request the specific title.
We hope this helps you make sure you get what you need in the catalog! If you have questions about placing requests or using the catalog, the librarian at your local WCCLS library will be happy to help.
