The Series Tab allows the user to group all studies from one series even if the studies cover multiple topics. 

Click on the Series Tab. 

On this screen, you may click on the desired icon - delete, edit or new.

Click on the green checkmark to either publish or unpublish a study.

Note:  When a series is unpublished, all the information is still stored in the database, but that series will not appear in the drop-down lists of series.

The use of Series is options, but if Series are used, they must have a SERIES NAME.  The rest of the information is optional.
