First, I want to compliment LOGOS for continued progress in tagging dictionaries/encyclopedias with LCV. It is very functional now and will only get better in the future.
I want to suggest the same approach with various Illustration resources already in Logos. Many are like a dictionary with alphabetical list of "topics" and LCV would be very useful.
I can provide a list of resources that lend themselves well to LCV tagging, if needed.
