Personal Names

Hi all, I have today off to concentrate on homework. So far I've focused on the personal names.

Yes, the main entry needs to come first from an authorized source, such as the Title page. Also not always is the fullest form of the name the one that is most commonly used. I know #4 has been discussed in the WIKI but I'm still not sure about that one, if the other 400's are necessary. In the ppt for personal names, slide 159 + mentioned adding other variant forms only if in same source and if adding information. So I don't know if both of the 400's are necessary for #4.

My other question is about fixed fields. Does anyone know about the Name field? A for Differentiated and B for Undifferentiated. Aren't they all A? Or is it only when there's a date as well? I've gone with the later, but I don't think it's right.

Also, I had to clean up the records from the file Dr. Bob gave us. The formatting looked messy and I had a hard time seeing what was there, especially for the fixed fields.
Okay, working on the corp names now....
