In-text citation for research paper. How to look for a "source" when a reference is an article on a website? I am an I.T. student and currently working on my capstone project it is equivalent to research paper or thesis for some college courses. I usually do an in-text citation using APA style. For example:


  According to Jones (1998), "Students often had difficulty using APA
  style, especially when it was their first time" (p. 199).


As you can see at the last part (p. 199) that is the "source". At least, that is what I understand from my professor's explanation. 

Since almost of my reference are taken from websites particularly an article which have no pages on it. My question is, how should I put a source in my research paper if a website have no pages?

I already do my research about this problem, but it is still very vague to me.
when you are citing a particular document or piece of information from a website, include both a reference list entry and an in-text citation. 

The key to creating the reference list entry is to determine the type of content on the web page. Basically, provide the following four pieces of information:
Author, A. (date). Title of document [Format description]. Retrieved from http://xxxxxxxxx

The in-text citation includes the author and date (Author, date), as with any other APA Style citation.

You can read more about this from the APA style guide website at: http://www.apastyle.org/learn/quick-guide-on-references.aspx 

Check out the "More Information" section for further clarification on what to do if there is no author, year or page numbers. 

I hope this is what you were asking.  Andy ;-)
