How to cite a phd thesis that was published as a book? What information is important to provide when citing from a PhD thesis that has appeared as book?


The publisher (even if it is a 'dubious' one that might vanish in the near future)
or the institution and that it is a phd thesis.


As for bibtex, I wonder whether I should use the @book or the @phdthesis entry type.
Provide the citation form that you think will be most useful to readers in the middle or long term, or provide both.

If it's self-published, then cite it as you would cite a thesis. On the other hand, if it was published in book form by a respectable publisher (i.e. it will be easy to find 10 years from now), then cite the book. This is commonly done in some fields of humanities.

Citing both is also an option, and it does not have a downside, except it's a bit longer.
