It is highly edificational to collect a few published series and see what
happens when you try to correlate them.


I suggest you don't take such series very seriously. Contact
electrification is super-sensitive to details of the surface state. For
example, glass with adsorbed moisture is radically (so to speak :-)
different from ultra-dry glass.

You can even set up a system where rubbing gently produces one sign of
charge, and rubbing harder produces the opposite sign.
