Bibliography format with multiple citations from same book? (APA) I'm writing a paper where I've included multiple citations from a book, each citation is not a direct quote from the text but rather a in-text citation.
According to APA guidelines, these citations should be at the end of the paraphrased text such as:


  My text here blob blob blob (Rubin, 2013).


Since these citations do not include page numbers (direct quotes do, according to APA guidelines) and I have three (so far) when I insert a bibliography with Word these look like this:


  Rubin, K. S. (2013). Essential SCRUM. Ann Arbor, United States of America: Addison Wesley.
  Rubin, K. S. (2013). Essential SCRUM. Ann Arbor, United States of America: Addison Wesley.
  Rubin, K. S. (2013). Essential SCRUM. Ann Arbor, United States of America: Addison Wesley.


So, my question is: Is it okay to have these duplicate entries in the list of references/bibliography at the end of the document or should I add the page number to both in-text citations and references, even though they're not direct quotes within the document but in-text citations instead. I hope that makes sense.
Normally duplicates are avoided. Also, your duplicates do not have a page reference and are therefore useless in this respect.

Whether or not you have to specify the page number, I would personally check with your supervisor to avoid misunderstandings.
