The West Philly-based Books Through Bars always needs paper bags for their packages. So if you are thinking of throwing those bags in the recycling, why not just stroll down to the A-space at 4722 Baltimore Ave. and drop them off. You can bring them on Tuesday evenings from 7:30 to 9:30 pm when they pack books, or slip them through the mail-slot on the A-Space door any time.
