Yesterday, I saw a post by M.J. where she attached an image of the Catholic Topical Index (see below), and I really liked the presentation of the references. At first I thought it was a feature unique to Verbum, but after looking around I found it in Guides. Reading up some more, I realized I had to purchase the Catholic Topical Index to get it to work, which I did.
However, while M.J.'s image shows the entries as topics (Holy Spirit/Trinity), mine (image below again) seems to only accept Bible references. Of course, I can go by way of the Topic Guide and select the CTI from there, but I'm curious why mine is working differently; is the ability to enter topics directly into the standalone CTI unique to Verbum or am I missing something?
