ISTR

What ISTR does

ISTR (the International Society for Third Sector Research) is a 501(c)(3) nonprofit scholarly association founded in 1992 and incorporated in Maryland, with a secretariat office in Seattle, Washington. It operates as a member-supported global community of approximately 900 academics, researchers, and practitioners across 80 countries studying civil society, philanthropy, nonprofits, volunteering, and social enterprise. The organization is run by a three-person secretariat (Executive Director Megan A. Haddock, Program Manager Beth Lovelady, and Administrative Coordinator Alexis Semeraro) under the governance of an elected international Board of Directors drawn from universities on five continents.

ISTR's core products center on a portfolio of scholarly publishing and convening assets. The flagship is Voluntas, an interdisciplinary peer-reviewed journal published six times per year that is transitioning to open access with Cambridge University Press in 2026, accompanied by a Conference Working Papers Series, Working Papers Features, and the Springer Nonprofit and Civil Society Studies book series (nearly 30 volumes). The organization runs biennial international conferences (17th edition in Lisbon, July 2026, hosted by Iscte) plus regional conferences in Asia Pacific, Latin America & the Caribbean, and Africa, supplemented by a PhD Seminar, Mentoring Program, affinity groups, five continental regional networks, and an awards program covering best papers, dissertation research, posters, three-minute thesis, and policy impact.

The business model is built on recurring multi-year membership dues (Individual $280–$560 over 2–4 years; institutional $600–$1,200; student and retiree tiers reduced; reduced-dues categories for lower-income countries), biennial conference registration fees and tiered sponsorships (Bronze $5,000 through Platinum $25,000+), publisher partnership discounts (Springer, Lynne Rienner, Bristol University Press at 25%), and charitable donations across four named funds including a planned Legacy Society. GTM is sales-led in the sense that membership is sold through self-service online application and renewal via the YourMembership platform, with conversion supported by regional network ambassadors, conference recruitment, and academic citation channels.

Expansion highlights6 records

Direct peers

• ARNOVA (Association for Research on Nonprofit Organizations and Voluntary Action): The most direct peer — a US-based scholarly association dedicated to research on nonprofit organizations, voluntary action, and philanthropy. ARNOVA publishes Nonprofit Voluntary Sector Quarterly, runs an annual conference, and serves an overlapping membership of academic researchers, with a more North American focus versus ISTR's global remit.

Broad incumbents

• Independent Sector: A US national membership organization bringing together nonprofits, foundations, and corporations to advance the charitable sector. Comparable as a membership-based civil society infrastructure organization, though more policy-and-advocacy oriented than scholarly research.
• WINGS (Worldwide Initiatives for Grantmaker Support): A global network of philanthropy-support organizations with comparable global reach and a focus on the philanthropic and civil society sector. Comparable in mission-adjacency (supporting civil society infrastructure) though oriented toward grantmaker support rather than academic research.

Regional players

• NCVO (National Council for Voluntary Organisations): The UK's umbrella body for the voluntary sector, providing research, policy, and infrastructure support to civil society organizations. Comparable in mission (advancing the voluntary/third sector) though operating at national UK scale rather than global academic scale.
• Philea (Philanthropy Europe Association): Europe's leading philanthropic infrastructure association representing foundations and grantmakers. Comparable in serving the civil society ecosystem across multiple countries, though focused on European grantmakers rather than global academic research.

Others

• Alliance for Charitable Philanthropy / Worldwide Initiatives for Grantmaker Support: Adjacent infrastructure organization supporting grantmakers and philanthropy globally. Comparable as part of the broader civil-sector institutional ecosystem that ISTR's academic membership studies, with overlap in convening capacity and global reach across the third sector.
• National Council of Nonprofits: A US network of state and regional nonprofit associations advocating for the charitable sector. Comparable as a nonprofit-sector infrastructure organization but with a US domestic policy orientation rather than ISTR's global academic research focus.
• Candid (formerly GuideStar/Foundation Center): A US-based nonprofit that provides information and research tools about the philanthropic and nonprofit sector globally. Comparable as a research-and-information hub for the third sector, though operating as a data/technology provider rather than a scholarly membership association.
• Council on Foundations: A US-based membership association for private, family, community, and corporate foundations. Comparable as a sector-wide membership organization serving the philanthropic community, though focused on grantmaking institutions rather than academic researchers.

Emerging players

• European Voluntary Sector & Volunteering Research Conference (hosted by various European academic centers): The annual Voluntary Sector and Volunteering Research Conference brings together European academic researchers studying the third sector — comparable in convening function and audience overlap with ISTR's regional conference programming, particularly the European and global biennial events.
