This digital humanities project aims to bring together numerous oral history repositories that can already be found online in a manner that makes them more visible and accessible to historians of environmental science. These repositories are diverse and range from large institutional archives to small and thematically focused collections.

EnvOH currently makes fully searchable a total of 212 records from the following 3 collections:
