Hello I am annotating seven Arabic texts and their translations into English, and I am thinking of a title for the annotation. So, I simply thought of the following title: ''Annotating the Poems and their Translations by Arberry and O'Grady''. Is this title grammaticaly correct? or should I replace ''by Arberry and O'Grady'' with ''of Arberry and O'Grady ''? Thank you.
