Thankyou katie_here...
This only highlights for me the need to make sure I do not presume that any abbreviations I may use are understood, but are to also be spelled out within my posts for the many within our growing community who may not necessarily read the same threads in which those abbreviations are assumed to be commonly understood.
Another abbreviation which is also used (especially elsewhere) for the deck by Waite and Colman Smith is W-S or W-CS. The appelation 'Rider-Waite' is simply the registered name by US Games for the deck which has its copyright expired - ie, not the deck, but the name is copyright by US Games, and even the Rider publishing company never used the term 'Rider Waite' when it published the deck in its earliest days.
Other names which are at times used to differentiate various Marseille style decks are by the name of the publisher, designer, or that used on a or some cards within the deck - such as Vieville (sometimes Vievil), Dodal, Noblet, Hadar, Camoin (sometimes, and more correctly, the Camoin-Jodorowski), Conver, Piatnik, Fournier, Grimaud, Marteau, Burdel ... & a host of others, at times without the more generic 'MARSEILLE(s)' word attached for those unfamiliar with the tradition to easily identify the same. Again, I will personally have to be careful as I am sure to have been somewhat remiss at times.
