Code # (No edition information recorded) was valid 1979-1987. Records created before the definition of the first indicator in 1979 may contain a blank (#) meaning undefined in this indicator position.
This value was made obsolete in 1989. The U.S. Library of Congress discontinued assigning class numbers from the abridged NST version to items included in New Serial Titles as of 1981.
Code # (No information provided) was valid 1982-1987. Records created before the definition of the second indicator in 1982 may contain a blank (#) meaning undefined in this indicator position.
Prior to 1975, the definitions of subfields $a and $b in the serials specifications were reversed: $a (DDC number-abridged NST version), $b (DDC number). This definition of subfield $b was made obsolete when the first indicator and subfield $2 were defined in 1979. The current subfield $b was defined in 1987.
