This study documents the experience of, and identifies professional barriers for, academic librarians and archivists with invisible illnesses and/or disabilities. Results from a survey of MLIS-holding individuals in academic positions indicate that invisible illness or disability often impacts the ability to succeed at work, but many are reluctant to disclose or request accommodations to alleviate those disparities. Respondents reported barriers including professional repercussions for disclosure, difficulty during the hiring process, stigma from supervisors and colleagues after requesting accommodations, and an overall lack of understanding about invisible illness and disability in the profession.
