# ACM SIG Template: unwanted ACM ISBN and DOI

I'm writing a technical paper and there's a small annoyance on the pdf of my paper. At the bottom of the first page in the footnote the text

ACM ISBN 978-1-4503-2138-9.
DOI: 10.1145/1235


appears. This text throws the formatting of my paper off significantly and it leaves a huge gap of white space towards the bottom of the first page. How can I get rid of this? Is it a problem with the document class "sig-alternate-05-2015"?

• Welcome to TeX.SX! Do you have any specific reason for using sig-alternate? – egreg Mar 30 '16 at 7:03
