Paul, on Ilio's site on the Solo Violin page, it says the following directly below the price and "Standard Library":
The Standard Library consists of essential articulations. The Full Library includes the Standard Library with additional articulations (usually 2-3 times more). Vienna Symphonic Library's greatest potential is achieved using the Full Libraries. You may purchase the Full Library, or upgrade to the Full Library after purchasing the Standard Library. Your price may be reduced after placing your order depending on other Vienna purchases.
I know this is boilerplate text, but it might confuse people into thinking there's more to come or an alternate, "complete" version of Solo Violin and Cello 2.
