HI! first post here so please be gentle.

I have a few questions relating to Calibre and the Kindle 3.

I have 500+books (mobi format) on the Kindle and would like to be able to view the book description without having the hassle of connecting to amazon each time.

I found that I can add the metadata to the start of each book which solves this irritation.

Do I have to convert each book in my calibre library so it includes the metadata or is there a way to add it directly to the books on the kindle?

If I convert mobi to mobi , will I have 2 x mobi files or will one be discarded in the process?

If I have to convert all my books so they include the metadata at the start of the book, would it be best to just delete the entire contents of my kindle 3 and resend them using Calibre?

Maybe I'm missing something here so if there is an easier way to read book descriptions ,please tell me.

Thank you for your time and patience.
