Question: Mathematics and Engineering dictionary in Maple

Just curious as to how to find the Mathematics and Engineering dictionary in maple. 

In Maple 12 it was available in the help menu as Dictionary, which then pulled up as a help menu with folders a to z. 

In Maple 2016, I only noticed today, Dictionary is no longer a help option in the pull down menu.  Searching for dictionary brings up some of the files in the help menu but not sorted beautifully as M12.  In fact there is a definition list but it ends at d.

Am I missing something or is there a dictionary fault?
