For example, if the title is a multi-volume title, each volume/issue will be a separate request group. If there are different material type items, each material type will also be a separate request group.

The request groups' parameters also include the allowed pickup locations and the information that may be attached to the request, such as additional author information or added notes. Such fields are marked by the usage attribute.
The resource may be accessed with a PUT method to create a hold request for a specific patron and on a specific title.
