'Ex Libris' usage
I'm putting 'Ex Libris' bookplates in all of my books, but want to order the bookplates by type. So far I have:
'Ex Libris Astronomicis' (from the astronomy books of)
'Ex Libris Computatris' (from the computing books of)
'Ex Musica' (from the music of)
I am also familiar with 'Ex Libris Eroticis' and 'Ex Libris Occultis' but I don't have any books like that yet.
So my question is, how would I say, in Latin please:
'From the music books of' (Ex Libris Musicalis?)
'From the science fiction books of' (Ex Libris Scientiarum Fictionalis??? guessing)
'From the history books of'
'From the children's books of'
'From the reference books of'
And what is the actual case used there with the ending -is please?
