I saw the roshei teivos החזו"א in the Dirshu notes to Mishna Berura in Hilchos Rosh Hodesh. Can you tell me who it is? Is there a general resource to figure this out?

@DoubleAA Thanks! That looks useful. Doesn't look like it'd've helped with this one. – Isaac Moses Feb 2 '14 at 18:34

I suspect that that refers to the Chazon Ish. The letters fit, and the Chazon Ish's rulings are often quoted alongside those of the Mishna Berura.

Thank you, you must be right. I was looking for a "Chaim Zalman..." or something. It was actually in the Dirshu notes, not the mishna berura itself for what it's worth. – Seymore Cohen Jan 31 '14 at 20:34
The Mishna Brurah would not quote the Chazon Ish,but dirshu would,and it is indeed the Chazon ish – sam Jan 31 '14 at 20:35
@SeymoreCohen In general, most sefarim have an index towards the front of the sources they have culled from. You can usually match up the roshei teivos to that list. – Y ez Feb 2 '14 at 2:12
