Yes, many such sources exist.  But a children's book that doesn't mention inverter, and uses other substardard terminology like putting gates ""in series"" is pretty unusual.  The Quantum Computing book is talk about something that is not an inverter, because it's a quantum gate, not a logic gate (read the description); so we don't really care what they call it.   The rest mention both terms.  I pointed out a book or two with discussions of logic gates that only use inverter.  Are there any that only use NOT gate, besides the children's book?   This search and this should clarify what is more commonly called what.   "
