Share settings with alternate library

Hello everybody,

I created a new calibre library for newly acquired eBooks I've not yet had time to prepare for my main calibre library.

However I cannot find in this new library any of my custom lists (including Genre, Language, Foreword, Translator, Tags, etc.) which are available in my main library.

How can I get them into my new library and take benefit of them?

Many thanks in advance for any helpful answer.

Take care.
