As for Welk, I'm a Cissy King man.
I don’t keep up on EVERYTHING in the field.
It’s grown far too much for that.
Besides, there’s a lot of redundancy at this point.
Given my early library worker years and childhood where books were my main friends . . .
I had a lifelong habit of reading a book literally cover to cover.
I don’t do that with UFO books any more. I know most of the background by heart . . . and almost every book has a chunk of that. And, I know a lot of the typical newer stuff by heart as well. So I just scan for the new parts I haven’t heard of yet. Saves a lot of time.
