I am working on US Federal Census records and cleaning up my sources. What information needs to go into each section of the citation details and text?
It is your decision what goes in there.
At a minimum it should be sufficient information to allow someone else to take your reference easily find the source document and check your transcription of the data.
Website links can be helpful but are limited in that websites can disappear and or pages get moved.
I always attach an image to my source citation and in that way the original doesn't have to be searched for BUT you must always include the id for the record, so state enumeration district etc.
There is a nice guide from ProGenealogists explaining how to do good citations of sources. I have nothing to do with them but I found their citation guide very useful.
I have done a series of Blog posts on this subject:
How to Display Data ?
I have been thinking about the ways we can display our data, usually for ourselves. For example, the 1940 Census.
