The UNLV Black Lives Matter Web Archive (2020) is comprised of two statements and one op-ed which were published shortly after the murders of George Floyd and Ahmaud Arbery and the subsequent rise of the Black Lives Matter movement. The statements come from Thom Reilley, Chancellor of Nevada System of Higher Education (NSHE), and Marta Meana, Interim President of the University of Nevada, Las Vegas (UNLV). Both statements express NSHE and UNLV's message of solidarity with the Black community and affirm the University's commitment to diversity, equity, and inclusion. The op-ed was written by UNLV alumna Jessica Walters Murrey who is a "social change and communication expert." The op-ed acknowledges Murrey's pain and grief and also outlines actionable steps that non-Black individuals can take to support the Black community.
