Open to publishing organizations and businesses (fee-based).

Publisher Members are entitled to the full array of benefits and services CHORUS  provides, notably a confidential dashboard for monitoring the open access status of your published articles reporting on funded research. In addition, you’ll have the opportunity to run for our Board of Directors and/or join our working groups, thereby contributing to CHORUS’ governance and helping guide our future. Membership also includes a listing and logo on the CHORUS website, as well as other opportunities to promote your membership.


About CHORUS’ Fees

Member fees (see current agreement, table, and notes below) are vital to CHORUS’ success—they cover our lean development and operating expenses. Yet they represent good value for our member businesses and organizations, amounting to much less of an investment than would be needed for your own open access compliance framework.

CHORUS is a service run by CHOR, Inc. an independent not-for-profit membership organization. CHOR, Inc. reserves the right to change these fees in the future. For General Publisher Member Policies, see Membership Agreement.

Notes on definition of “Total Publishing Revenue”

  1. Total Publishing Revenue includes all publishing revenue from all the divisions of an organization (primary and secondary) for all types of activities (advertising, books, journals, databases, article charges, etc). For membership organizations, member dues allocated to subscriptions will be included in total publishing revenue.
  2. For organizations that publish scholarly information as an ancillary activity, such as government organizations, the higher of either (1) total expenses for publishing operations or (2) gross publishing revenue should be used in determining the appropriate membership fee.
  3. The member is considered to be the largest legal entity rather than a division. Membership fee billing will be done on a calendar year basis.
  4. Members will self-categorize.
