The 1930-1985 Index on the 2013 WTLIB definitely has references to "li" which is the "Life Everlasting" book from 1966
Sorry, can you provide an example?
For example, if I type in "Victim twisted on cross" there is 1 result, which is what I was looking for, the Aug 15, 1987 WT.
Now, if I type in "How appropriate it would be for Jehovah God" which is par. 43, page 30 of the Life Everlasting book, it doesn't show up.
