Cite the Web PDF in the text of the paper with the name of the PDF and the author of the file. By citing directly (not with a parenthetical citation) you introduce the reader to the resource within the essay itself.
Create an in-text citation by putting the author and the year the Web PDF was published in parentheses after referencing the source. Data sets often have an organization as an author instead of a person. For example: (Austin Film Festival, 2010).
Cite the Web PDF in the reference list with the author of the file, the publication date, the title of the PDF, the phrases "data file" and "retrieved from" and the website address where the web PDF came from. For example:
Austin Film Festival. (2010). Teleplay Application Instructions [Data file]. Retrieved from http://www.austinfilmfestival.org/datasets/2009application.pdf.
