crl-10454	Rider, Fremont	Microcards and Punched Card Filing	1949	3	.pdf	application/pdf	1814	68	61	I have had to reply that the filing of microcards, or for that matter the filing of any sort of catalog cards, was not practicable by any of the punched card systems with which I was familiar, and in the case of most of these letters I tried to explain why. Proponents of the mechanical filing of catalog cards have failed to realize at its full value the fact that all punched card systems were developed to be, and still are, sorting systems, not filing systems.	cache/crl-10454.pdf	txt/crl-10454.txt
