abbrevations: t.z.w. wne rys. r.n.e. ark wyd kl.

Hello! Can somebody tell me what these abbreviations mean:
t.z.w.
wne
rys.
r.n.e.
ark
wyd
kl.

I trip over them frequently everywhere, but haven't found in dictionaries. I hope they have something meaning...

t.z.w. - tak zwane - so called
rys. - rysunek - drawing or illustration
ark. - arkusz - sheet
wyd. - wydawnictwo - publisher
kl. - klasa - class (as in classification in botany, species, etc)

Not sure of the other ones

should be tzw.

r.n.e. - roku naszej ery - year AC (after Christ)
p.n.e. - przed naszą erą - BC

kl. - klasa - school class (not room but year)

wne - have no idea, but might be "w.n.e." - wieku naszej ery - century AC

Dziękuję bardzo za pomoc!! :DD

Abbreviations are tricky to work out sometimes.
