does anyone know what the difference is between "studies in tape reading" written under the richard wyckoff name vs. the one under the rollo tape name? http://www.amazon.com/s/ref=nb_ss_/...eywords=studies+in+tape+reading&Go.x=9&Go.y=6
None. Rollo Tape was the pen name Richard Wyckoff's used when he first published Studies in Tape Reading++
