We sincerely thank our sponsors for supporting American Journal of Undergraduate Research. We display our sponsors’ images with links on each AJUR web page. We also provide a page size ad in every issue of AJUR for organizations and individuals supporting AJUR. American Journal of Undergraduate Research (AJUR) is an independent, faculty peer-reviewed, open-source, no-cost-to-authors, quarterly, multidisciplinary student research journal, established in 2002. The journal obtained the formal Library of Congress web ISBN 2375-8732 and .org web presence in 2014. By the invite in 2015, AJUR has been retroactively internationally indexed by EBSCO. In 2018, AJUR was incorporated in New York State as an independent not-for-profit organization. In 2019, AJUR was registered by Crossref as an organization entitled to provide DOI numbers to all of its articles. AJUR‘s entire content, by the invitation in 2019, is archived by the United States Library of Congress. In early 2021, AJUR was registered as a charitable organization by NY State (NYReg# 48-18-81) and as a 501(c)(3) (EIN 831726417) under IRC by the US Department of Treasury.
