Data Bank with a Partial Computer Assistance

This system, which is especially intended for medium size data banks, benefits by both the flexibility of the deck of cards and the power of the computers. The bibliographical references are written on cards including a punch field, and computer assistance is used for punching, updating and selection. Card File.

As it is common practice, bibliographical references are put on cards. Using standard punch cards, about half the available field (preferentially right half) carries written information. In addition, the remainder (about 40 columns) carries punched information in binary format so as to restrain it within a minimum space (3 bytes every 2 columns). A preferred format used to store information is the following: - year of publication as a complement to 100 (uses 6 bits) - reference number (uses 10 bits) - initial and names of authors, limited to 50 characters, one byte per character (period after initials, comma after names, firm

names between brackets) - encoded references (up to 4).

Every reference is made of 2 bytes or 4 four-digit-sets, corresponding to four levels of generality in the Skeleton. Initial Card Punching.

Key punching in binary format would be cumbersome. The procedure being implemented is sandwiching reference "blank" (but written) cards with cards already punched in standard format, which uses the whole field. Any computer such as an IBM System 1130 with the minimum configuration can copy the punched card on to the bl...
