Crossref makes research outputs easy to find, cite, link, and assess.
We’re a not-for-profit membership organization that exists to make scholarly communications better. We rally the community; tag and share metadata; run an open infrastructure; play with technology; and make tools and services—all to help put scholarly content in context.
It’s as simple—and as complicated—as that.
Getting the community working together to make scholarly communications better
Structuring, processing, and sharing metadata to reveal relationships between research outputs
Operating a shared, open infrastructure that is community-governed and evolves with changing needs
Engaging in debate and experimenting with technology to solve our members’ problems
Creating tools and services to enable connections and give context
These are the Crossref ‘truths’, the principles that guide everything we do. Read our truths page, with full descriptions for each.
We started in January 2000 with one employee, Ed Pentz, as Executive Director. Read about our history in Ed’s words. Since we started we’ve grown to (as of 2019) thirty eight people, 13513 members, coming from over 120 countries.

We are sustained by [annual membership fees](/fees#annual member fees) that are tiered according to size of publishing revenue. We also charge a [content registration fee](/fees#content registration fees) for each item of content whose metadata is deposited with us. We also provide both free and paid-for [metadata delivery](/services/metadata-delivery) options for access to this metadata. Members can and do [participate](/community) in many ways and contribute to our global network of linked scholarly content. We are governed by sixteen of our members that form [our board](/board-and-governance) serving three-year terms. We invite from each of the elected sixteen organizations, one main person as board member, and one alternate person. We also have other committees that help us [set fees and policies](/committees/membership-and-fees), [audit us](/committees/audit), and an [Executive Committee](/committees/) that meets more regularly and supports the Executive Director in making some decisions. You can read more about our finances and governance as well as what we worked on most recently, by viewing our [annual report](/annual-report). --- ## Workplace Equity Project
Crossref supports the Workplace Equity Project which is capturing data on workplace experience and practice throughout the scholarly publishing community.
Crossref was awarded the SOC 2® accreditation in 2017 after an independent assessment of our controls and procedures by the American Institute of CPA’s (AICPA).
The SOC 2® accreditation is awarded to service organizations that have passed standard trust services criteria relating to the security, availability, and processing integrity of systems used to process users’ data and the confidentiality and privacy of the information processed by these systems.
The AICPA’s assessment also reviewed our vendor management programs, internal corporate governance and risk management processes, and regulatory oversight.

These are the Crossref truths. These are the principles that guide us in everything we do. They were tested with members and adopted by our board in 2016. We tweaked and added “What you see, what you get” in 2017. Come one, come all We define publishing broadly. If you communicate research and care about preserving the scholarly record, join us. We are a global community of members with content in all disciplines, in many formats, and with all kinds of business models.
Crossref is registered as Publishers International Linking Association, Inc. (PILA) in New York, USA. You can view our certificate of incorporation and by laws. We have tax exempt status in the US as a 501(c)6 organization. Here is our antitrust policy and our conflict of interest policy. The board of directors governs Crossref. They meet three times a year and oversee the organization, set its strategic direction and make sure that Crossref fulfills its mission.
Come work at Crossref. It’ll be fun! Help us achieve our mission to make research outputs easier to find, cite, link, and assess. We’re a small but mighty group working with 13513 members from 120 countries, and we have thousands of tools and services relying on our metadata. We take our work seriously but usually not ourselves. We have offices in Oxford, UK, and Lynnfield, MA, USA, but actively seek remote/home-based people too.

We are a small team of jovial and diverse individuals who all share the common goal of moving walls… literally and figuratively.

Finding ways to help organizations participate in our services is an important part of what we exist to do. We know that cost and technical capabilities can be barriers to participation, and we aim to provide assistance with these in a number of ways: Sponsor arrangement. Our Sponsoring Organizations can help members join Crossref by providing billing, technical and administrative support. The Sponsoring Organization pays a membership fee to cover the organizations it works with (some may charge for the services they offer).
We like to share information about our operations in a transparent way, in keeping with Our truths. Here is our latest annual report. It includes information from each Director and our board’s Chair and Treasurer. It also gives data of both the metadata and financial varieties, and includes related governance information.
