I was mistified when my Anchor Yale Bible Dictionary was no longer coming up in the Exegetical Guide to Logos 4. The new platform is even easier and I hope this helps other users:
Right click on the word from the preferred Bible (either in the text or in the box of Lemmas, etc) and a menu will come up with the English lexicons named at the bottom for the particular word. If the word is "heaven" then the Anchor Yale Bible Dictionary will be among those named, if you have that in your library. It is a wonderful resource and sold in the products section of Logos.
I also just found out that my favorite English Dictionary: Noah Webster 1828 is sold in the Logos products listed under: The Christian History Library. The KJV becomes so much clearer when used in conjuction with the original Webster's 1828.
There was a previous feed on this topic that got moved by Gerda Pesswir to a site that sells the Anchor Bible. I am mistified by that too. Hope this helps someone else today.
Blessings to all and especially to all those who are helping answer questions about Logos 4. The program has a learning curve but it is AWESOME.
