Instructions for Authors of Refereed Papers

  1. Final papers deadlines. A printable PDF of your paper is due via the submissions system on or before Wednesday, June 9, 2021. These are hard deadlines. No extensions will be granted. If you have questions about the requirements shown below, contact the Production Department.
  2. Maximum page length. Final papers must be no more than 12 pages (excluding acknowledgements, bibliography, and appendices) and up to 20 pages total including acknowledgements, bibliography, and appendices.
  3. Paper format. Papers must use the SOUPS formatting template (available for MS Word or LaTeX), and be submitted as a PDF via the submission system by June 9, 2021. If you have questions, please contact the USENIX Production Department.

  5. Make searchable your final paper PDF.

  7. Certify your final paper's title, author, and abstract in HotCRP. The final PDF's title and author information, including author order and affiliation, and the abstract, must exactly match the information entered into the HotCRP submission system. Please update the information in HotCRP as necessary, then check the certification checkbox. Please note: if you make any changes after you check the certification checkbox, you will need to check the box again.
  8. Sign the consent to publish form. Each author must sign a consent to publish form, which allows USENIX to publish the paper as well as any slides, audio, and/or video of your presentation. USENIX makes these freely available as part of our commitment to open access. Please review and e-sign the form. If you are the lead author, please be sure all of your co-authors sign a form.
  9. Use of images, audio, and video in your materials. It is very important that you secure permission to use copyright-protected materials in your slide deck, paper, or other materials used at a conference or submitted for publication. Even when an item has a Creative Commons license, you must read and comply with the terms of the license.

    USENIX receives copyright infringement notices from time to time, resulting from authors or speakers using copyright-protected materials without proper licensing or attribution. When this happens, we have to depublish the work in question until/unless the issue is resolved. Licensing fees may be incurred, even when the work is unpublished, and USENIX will bill the author or speaker for any costs incurred. When possible, USENIX will refer the complainant directly to the author or speaker, who will be solely responsible for resolving the complaint.
  10. Embargo requests. All papers will be available online only to registered attendees before the conference. If your accepted paper should not be published prior to the event, please notify the Production Department. The papers will be made available online to the public beginning on the first day of the conference.
  11. Prepare and submit your presentation videos and slides. For our virtual events, authors are required to record videos of their presentations and prepare their slide decks prior to the conference. Submit your videos and slide decks via our Box upload link by Tuesday, July 20, 2021. Specification requirements for both the videos and slides are available below.
