I'm trying to figure out if I have an apocryphal text called "The Acts of Paul and Thecla" in my library, but when I do a search on that title, it points to, say, an Ante-Nicene Fathers volume where that text doesn't actually show up that I can see. I find that a little frustrating - do I have it or not? It's happened in the past for other texts too.
Can anyone help suggest a better way to accurately figure out if I have a certain text in my library or not? Perhaps some method that I haven't thought of, but which will yield more accurate results? Especially when that text may simply be a "subtext" of some sort within a larger volume?
Thanks!
