As 440 cannot be controlled in OCLC, I change it to 830 and the control for series works. So I have a silly question, as to why not use 830 in lieu of 440s? That way this 490 1 issue can be avoided. It maybe a change the programmers can do without much hassle. --angelina Joseph Marquette University Law Library Milwaukee, WI 53201 Coding for 490 first indicator definitions: 1 - Series traced in 8XX field When value "1" is used, the appropriate field 800-830 is included in the bibliographic record to provide the series added entry. Does this mean that if the series statement is identical to the heading, field 8XX is simply repeats field 490 1? This is the way in which LTI handles series validation but it certainly makes for an illogical-looking and somewhat confusing record. Why was it thought necessary to abolish field 440? ============================ Kenneth Dinin Senior Cataloger Thomas J.
