[ModLib] Anybody know condition standards for ephemera?

[Scot Kamins]

Hi Folks,

I'm trying to find condition standards by which to judge/label  
catalogs with paper wrappers (such as all ML catalogs). Are the  
standards the same as we use for books, or are there separate "paper  
ephemera"  standards? If separate, is there a definitive web page on  
the subject?

Thanks,

Scot Kamins
