crl-12432	American Library Association, 	Letters	1972	2	.pdf	application/pdf	738	24	52	A sampling of our public catalog was carried out last summer to find the amount of filing error; the average error in both the author/title and the subject catalogs was estimated at 1.04 percent, at a confidence level of 95 percent. I, therefore, urge the edi- torial board to consider the adoption of a plan to include in CRL detachable and indexed abstract cards.	cache/crl-12432.pdf	txt/crl-12432.txt
