Each Tab in the Minute Book contains one or more documents. You can see the list of documents by clicking on the plus sign (+) of the applicable Tab. Once you do that, you will see the complete list of documents under that Tab as well as the Effective Date of each document (in the following format: yyyy-mm-dd).
Just click on the Minute Book document in the list that you are interested in; it will then appear in the viewer on the right side of the Minute Book page.
