In SharePoint 2007, how can I include some common items in a list, and some unique ones for each instance of the list?

Yes, use a list that includes multiple content types. You can define custom content types at a site level and they will be available within that site and all sub sites. You can enable content types on a list or library and include multiple content types for that list or library.

You can also have a content types in several lists and libraries.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
