I interviewed for an academic library position a couple of weeks ago. At the end of the interview, the head of the search committee told me that they would notify me about their hiring decision by a certain date. Unfortunately, I did not hear anything from the search committee on that date. After a week, I called the head of the search committee and left a voicemail message asking if they were still working on their hiring decision, or if they had already filled the position. Another week has passed and I still haven't heard anything back--no email, no phone call, no rejection letter.

Would it be appropriate to follow up one more time with an email? Or should I just assume that I didn't get the position and drop it?

I'm also wondering if this is standard practice? I know lots of libraries do not send rejection letters to their entire applicant pool, but is it common to totally ignore someone after an interview?

I agree with Hollis, they may have had some issues arise that might have prevented them from responding in the time frame they originally indicated.
