FILING

As noted ear lier, in au tomated libraries no fil ing needs to be done.
The com puter is pro grammed so that all ac cess points are in dexed
and, there fore, re trievable. Libraries with cards to file in the cat alog
should fol low the rules in ALA Fil ing Rules, 1980, published by the
American Li brary As sociation. Some of the most ba sic and most
commonly used rules are sum marized in Fig ure 9.1. Fig ure 9.2 shows
ex am ples from the ALA Fil ing Rules, 1980. When in doubt, this ref er-
ence should be con sulted.
Though there may not be shelflist cards to main tain, it is im portant
to learn how the call num bers are filed in or der, since this is the way
materials are shelved. Dewey call num bers are filed by clas sification
numbers first. For the same classification num bers, the au thor num -
bers are com pared, first al phabetically, then by dec imal num ber. The
following is an ex ample of a cor rect se quence:

010 010 010.01 010.1 010.1 010.1
.A19 .A2 .A131 .A121 .A13 .A13

Keep in mind that all au thor num bers fol low a dec imal point, even
though the dec imal points mis takenly may not have been printed on
spine la bels or on cards. There fore, for two items with the same class
number 010, au thor num ber .A19 is filed be fore .A2.
