Description/Instructions:
These companion fixed field elements consist of four character positions (c.p.). The NATURE OF ENTIRE WORK code signifies that the serial is composed entirely of a certain type of work. The NATURE OF CONTENTS code indicates that the publication contains items, but does not consist solely of any one of them. When c.p. 24 is coded, c.p. 25-27 must be blank and vice versa.
On the OCLC screen a circumflex (^) indicates the four character positions for these elements. When a code is input in c.p. 24 the code replaced the circumflex. When codes are input in c.p. 25-27, the circumflex remains on the screen.
DEFAULT CODE: ^###
C.p. 24:
Input only one code in this element to describe what a publication is. For example, a serial which is a directory would be coded "r" in this position. However, if the serial contains a directory and other types of material, the code "r" would be input in c.p. 25-27. Example:
C.p. 25-27:
Input up to three codes in alphabetical order to indicate what a serial contains. If a serial contains more than three types of material, input codes for the three most significant. If fewer than three codes are assigned, input from left to right. If a code has been assigned to c.p. 24, c.p. 25-27 must be left blank. Example:
NOTE: University calendars (code "t") and Other reports (code "x") are not separately identified in the MARC communications format. Codes "t" and "x" are input by NLC, displayed on NLC records, and returned on tape to NLC. The codes are converted to "#" for distribution to and from LC.
