My significant other brought home a box of "new" Kirkland glossy paper 8.5x11, made in 
USA.  I can compare the visible qualities with the original Swiss version, but I do not know 
how to determine whether the paper and/or coating is acid free.    I searched the archives but 
didn't find any helpful comments on the new paper.     Does anyone know anything about the 
"acid" status of the new paper?

Thanks.
