There is no "extended" label on any box. If the term confuses you, you probably only have the standard library. The extension of any library - normally - gives you more articulations of the instruments you already have in the standard library. For instance, in the solo strings standard you have only sustain with vibrato, the extension gives you in addition: sus w/o vib, with progressive and with fading vib.
In the Special edition it’s not more articulations, but additional Instruments, like the chamber strings.
Due to the compresion-algorithms the extension is ALWAYS installed together with the standard lib, AND you instantly get a demo-licence for the extension, so you can see and use ALL instruments of the SE ext. in the beginning, but after a while (depends on how often you use them) they disappear (although they are still physically stored to your HD. You can see a small "l2" (Level2) sign next to the extended patches, and you see a "+" sign next to matrices which use l2-articulations.
Or: if you spent around 330 EUR for the SE you only got Std., if you paid around 720EUR you also have the ext. patches (just SE, the same prices go for SE+)
You don’t buy the extension physically (as they are already on your HD), but you buy an activation code for you eLicencer.
Of course the Appassionatas have a std. and a ext. lib as well. You can buy them from some sellers as "bundle", but it’s just like buying std. and ext. at the same time.
App I are regular played strings, App II are played muted (con sordino).
I STRONGLY advise you to go to the descriptions of the libraries here on this site, by clicking on "sample content" you can clearly see, which samples you get in the standard library and which you get additionally by buying the extended library on top.
