אעדיף כל שמונה is a set of piyutim by R' Elazar Hakalir for a weekday Shemoneh Esrei of Chanukah. It was apparently said in Ashkenaz into the Middle Ages, but didn't make it into printed siddurim.
I can't find its text online anywhere except this page, which I find very hard to read. Is there a more usable source?
