Not all zines will have an author listed but you can attempt to find as much information as you can by reading through the zine. You can also try searching for the zine online and see if you can find any specific information about it. More and more zines are being cataloged at libraries across the globe so it is worth a shot to Google.
Sometimes folks purposely do not put their name on their zines. Sometimes folks even use pseudonyms to protect their identity. When citing zines, we should always respect the author's privacy. Even if you know the author of the zine, do not put the author's name down in your citation if it is not listed on the zine itself. The same goes for using an author's real name in your citation if they write under a pseudoynm.
Include the word 'zine' in the citation. You will put the word 'zine' in brackets after the title.
If the zine does not have a volume/issue number, or a city of publication, leave those parts out of your citation. The goal is to make your citation as complete as possible with the information you have.
Example of a zine with an author, date, and place of creation:
Grey, N. (2015). Cure Huntington's Disease. [zine]. Salem. MA.
Example of zine without an author:
Life after the red zone [zine] (2017). Boston, MA.
Example of zine without author, date or place of creation:
If you see something, say something: 12 things to do instead of calling the cops [zine].
An in-text citation lists the author's name of the source you are citing and gives the page number in parenthesis at the end of a sentence. You might have to count the page numbers in the zine as most creators do not number their pages.
Example:
According to Wade (2018), the fact that research is done by humans is the biggest problem as researchers' "interests shapes who and what gets researched" (p.9).
