I had created a PB which I'd set the author of to "Forsyth, P.T."
I switched to my Library (which was already open in a floating window) and typed author:"p. t. forsyth"
I realized that all the Logos edition books by him in my library are listed under "Forsyth, Peter Taylor".
So I went back to my PB tab and changed the author of that PB to "Forsyth, Peter Taylor" and clicked "Build book" to rebuild it.
While that was still building, I switched back to my Library.
I observed it flashing like crazy. See video:
