I'm currently working on my thesis (communication science), and I'm wondering about the issue number in the reference list.
A teacher told me that I don't need to include the issue number. But I can't find anything about it, so I wondered if somebody here knows about it.
The current mark-up that I'm using now is as follows (I mainly cite scientific journals):
Lastname1, Initials., & Lastname2, Initials. (Year). Title. Journal name, volume number (issue number), page-page. DOI / Link
Can I exclude the issue number or is imperative to include it?
