The Yale Survey: A Large-Scale Study of Book Deterioration in the Yale University Library	1985	22	.pdf	application/pdf	11645	579	64	Each nine-digit code identified a particular book by stratum (two digits), range number (two digits), section number (two digits), shelf number (one digit), and book number (2 digits). Since a pH of 5.4 or below is very acidic (i.e., well below neutral), the percentage of acidic books identified in the survey is conservative.	cache/crl-14090.pdf	txt/crl-14090.txt
