Thank you for your question. Your concern about readability of a third grade math book is appreciated, however there are currently no guidelines incorporated into the Promising Practices document regarding a book following Nemeth code. The Nemeth Code does not address the topic of a Special Symbols page but it is common practice to list only transcriber-devised symbols. However, since you are following the guidelines in Promising Practices, I see no reason not to list the type-form indicators (both literary and Nemeth) used in each volume. Note that, with judicious application of NC Sec.34b, much of the non-regular type found in the print book may be arbitrary.
