first off: I will very much try to do this myself. I'll probably fail epicly but at least I will have tried :)

If you look into my post history, you will notice I am (forced to) create my own APA-style. My university is very strict on this and points will be deducted if you miss against their citation-laws... During a draft-meeting of my current paper, I was pointed to such a failure.

I would like to use this book in my paper. As you can see, the APA-style is mentioned so this should be a breeze...

However, this book was created in 1947, but it is an edition of a text from back in 1626. Therefor, we have to use the special-invented-university-format:

EDITORS (ed.) (YEAR). AUTHOR. TITLE. (EDITION). PLACE: PUBLISHER.

Meertens, P.J.,N.B. Tenhaef & A. Komter-Kuipers (ed.) (1942). Adrianus Valerius. Nederlandtsche gedenck-clanck. Amsterdam: wereldbibliotheek.

It gets even better :( - If you point to a chapter (The life of Adrianus), written by one of the EDITORS (Meertens), that should also become an entry in the bibliography:

AUTHOR_OF_CHAPTER (YEAR). 'TITLE_OF_CHAPTER'. In: WORK_ABOVE

Meertens, P.J. (1942). 'The Life of Adrianus'. In: Meertens, P.J.,N.B. Tenhaef & A. Komter-Kuipers (ed.) (1942). Adrianus Valerius. Nederlandtsche gedenck-clanck. Amsterdam: wereldbibliotheek.

This! however, should not be confused by a book with multiple writers. Notice (the total lack of) difference :/

The correct citation for this book is

AUTHORS (red.) (YEAR). TITLE. (EDITION). PLACE: PUBLISHER.

Absillis, K., Jaspers, J., & Van Hoof, S. (red.). (2000). De manke usurpator : over verkavelingsvlaams. Gent: Academia press.

Jaspers, J. (2000). 'Some chapter'. In: Absillis, K., Jaspers, J., & Van Hoof, S. (red.). (2000). De manke usurpator : over verkavelingsvlaams. Gent: Academia press.

now: the question

How can I have biblatex differentiate between these two different type of @books? Can I program a macro in such way that it checks for

• This book has an author and a (or multiple) editors => must be type 1, format accordingly


• This book has only editors => must be type 2, format accordingly

OR! Can I have Biblatex checks for a custom tag "type = {TextEdition}" I can add to the type-1 books?

And YES: we make the distinction between a book with multiple authors and a book with multiple editors :/ And my second example (the usurpator) is an example of a book with multiple editors, according to our holy formatting bible...

EDIT: a book with only editors is a collection, according to zotero. So I need to differentiate between a

• This book has an author and a (or multiple) editors => must be type 1, format accordingly


• This book has only authors => must be type 3

the working example:
