AUTHOR/EDITOR OR 100/700 FIELD
100 vs. 700 field
100 field – This is a personal name used as a main entry. It should be the first listed author on the title page.
700 field – This is a personal name as an added entry. Authors listed after the first will be in the 700 field. Editors always go in the 700 field – never the 100. Writers of introductions, forewords or prefaces (esp. if they are well known), illustrators, curators, etc., if they are noted on the title page, are sometimes traced here.
How the title page, the 245 field and the 100/700 fields relate to one another:
The 245 field should match the title page exactly in regard to personal names. If the names in the 245 don’t match exactly with the 100/700 fields, there a few things to consider.
The Library of Congress Name Authority File is “a comprehensive controlled vocabulary (established list of preferred terms, with cross references), primarily of names and jurisdictions, used by thousands of institutions to describe and index persons or bodies who are the subject of, or responsible for the intellectual content of library and archival material.”
The 100/700 fields are authority controlled fields and great care must be taken with them because a patron’s ability to find a work through the author (or editor, etc.) depends on their accuracy.
First, if the names in the 245 don’t match the 100/700, determine in what way they don’t match and if any action needs to be taken.
No action is needed if the 100/700 reads: ‘Anderson, Kevin B.’ and the 245 reads: ‘Anderson, Kevin’, the patron will be able to successfully look up the book by author regardless of which form (with or without the middle initial) of the name they know, because the authority field is inclusive of both.
If the situation were reversed and The 100/700 read: ‘Anderson, Kevin’ and the 245 read: ‘Anderson, Kevin B.’, the patron would fail to retrieve the record by searching ‘Anderson, Kevin B.’ unless the authority record contained a cross reference that included his middle initial.
There are other instances when the authority record needs to be looked at to make sure the appropriate cross references exist. (In these cases, if there is no authority record, the cataloger will download it from Connexion.)

Name order unclear – sometimes the name order in the 100 field will differ from the 245 – the authority record needs to reflect this:
