Like you said each to their own..

The only reason I like to have a main author for some books is when it comes to a series. I really hate seeing in say a stephen donaldson folder 5 of 7 books from a series there but due to naming the other two are found in a different directory.

While Calibre is running its not an issue but I like to see them in one spot.

I liken it to having a chess set - all the pieces are on the board except for say two sitting somewhere else.

Great having this conversation - good to see what others are doing and how there going about their cataloguing.

Cheers
