TIP of the day: Indices and search fields
For resources to be in a parallel collection, they must have a shared index. To determine what indices a resource has, look at the Indexes section of the Resource Information Panel.
Similarly, to know what Search Fields are available in a resource, one may look at the Search Fields section of the Resource Information Panel. The advantage of this over the drop-down selection in the Search panel is that it provides a definition of the fields.
Here are screen shots from the following which are a single resource in the print edition.

Any item that can be used in the reference box of a resource, will be a data-type with an index on it. However, not all indices may be used in the reference box.
