The Reference Browser is like a Scripture reference index in the back of a print book. Use it to locate occurrences of Bible verses in any Libronix e-book.
For example, open the Logos Hymnal. Now open the Reference Browser from the Go menu or use the keystroke shortcut Ctrl + R. Set the In box to the Logos Hymnal and the Type box to Bible. Type “Rev 19″ in the Find box and click Search.
You’ve just found all of the hymns based on Revelation 19.
