coeditar

To co-edit — jointly prepare a publication, book, or academic work for release together with another editor: coeditar un libro, una revista coeditada por dos universidades. Common in publishing and academic contexts.

• Las dos editoriales coeditaron el libro de poesía. — The two publishing houses co-edited the poetry book.
• Coeditó la revista académica durante diez años. — She co-edited the academic journal for ten years.
• El diccionario fue coeditado por varias universidades hispanohablantes. — The dictionary was co-edited by several Spanish-speaking universities.

Coeditar refers to shared editorial responsibility for a publication, not to editing video or audio, where editar alone is used regardless of how many people work on it.
