About CISS

The Canadian ISBN Service System (CISS - pronounced "kiss") provides Canadian publishers with a number of free key benefits:

  • A convenient, easy to use online ISBN logbook;
  • Continuous 24-hour access to their ISBNs;
  • Increased options to send their ONIX bibliographic data to their supply chain partners in XML or Excel formats;
  • Improved management of their present and future titles and ISBN assignments;
  • Faster ISBN transaction times;
  • Access to a technical support line; and
  • Future potential to accept batch submission of bibliographic data.

Instructions on using CISS effectively are provided in the Help section of this website. The Help section outlines the steps required to:

  • register;
  • obtain a user ID and user password;
  • access and use CISS;
  • request an ISBN block;
  • assign an ISBN;
  • update your Publisher Profile; and
  • enter your title and bibliographic information.

The latest improvements allow publishers to upload bibliographic data utilizing the canadian bibliographic standards or ONIX records. We encourage you to visit for more information regarding ONIX the following website:

As such, publishers can upload all of their ISBN prefixes in one file into CISS providing it meets the canadian bibliographic standards.

We strongly encourage you to use CISS and familiarize yourself with Library and Archives Canada's new electronic environment for Canadian publishers.
