# Dates not printing using BibLaTeX [closed]

I'm using biblatex to process the bibliography for my dissertation using APA. The problem is that dates are not being printed; the dates are being replaced by a n.d. and this is not correct because my .bib file has dates.

This is my MWE:

\documentclass{article}

Several policy mechanisms have been implemented to reduce social, ethnic, and gender disparities in STEM education, including scholarships or loans for promising students, and alternative admission policies. A more recent policy mechanism, however, seeks to develop a pool of suitable individuals from traditionally underrepresented groups in STEM who can become faculty and mentors. This approach---known as the Alliance for Graduate Education and the Professoriate (AGEP)---resonates with research and anecdotal evidence that suggests that faculty who share the same background as their students can serve as effective role models \parencite{Carrell2010} since they are in a better position to understand their needs, expectations, and challenges, and this, in turn, can translate to higher enrollment and retention rates, and better race relations on campus \parencite{Alger1999, Dubin2000, George2001, MacLachlan2006}.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  egreg Apr 27 '13 at 20:27
You probably have compiled the document prior to updating biblatex (that's what the warning implies). Perhaps you should try to delete the biblatex control file (the .bcf file) and recompile your document. –  henrique Apr 27 '13 at 20:48
From the first \parencite{Carrell2010} I get "(Carrell, Page, & West, 2010)" –  egreg Apr 27 '13 at 21:17
I don't. That's why I'm posting the issue. I get "(Carrell, Page, & West, n.d)" –  user2167799 Apr 27 '13 at 21:23
I reinstalled biber and biblatex and I can see dates now. –  user2167799 Apr 28 '13 at 13:50

Important test could be style=authoryear

try this

\usepackage[backend=biber,style=authoryear]{biblatex}


and see if it works. That should definitely work. Unfortunately, it is a different type of citation and you obviously would like to have APA and not humanities-style citations. The reason I suggest this is because you can use it as a test on your system. If it fails to produce an output with years, then it is likely that your typesetting system has a problem.

egreg's comment of \parentcite is correct + henriques recompiling suggestion.

FYI, I just typeset the original code provided in your post and I saw dates, not n.d. (no date)

Order of commands:

1. xelatex
2. bibtex
3. xelatex
4. xelatex
