Who am I ? by Vincent von Ableben (best ereader for students TXT) 📕

A Riddle Poem:
Maybe this is not the first of its kind but at least it's mine. But not about me.
Find out for yourself.
If you have the (or at least a) solution, please do not write it into the commentary fields (so that others keep the fun for riddling theirselves) - but you may send me a PM, if you like.
