Library Services for Lamont-Doherty Earth Observatory Users

Library services supporting LDEO students, faculty and researchers continue from the Morningside campus with a courier service delivering library materials to a pickup shelf located in room 106 Geoscience (DEES Office) on the Lamont campus. The courier service will deliver on Tuesdays and Fridays. Library materials may also be returned via a drop-off box in the same location.

Lamont-Doherty Open Access Resolution

As of March 1, 2011, the Lamont-Doherty open access resolution requires all Lamont-Doherty Earth Observatory researchers to deposit their scholarly publications into an open access repository. Any article submitted after that date that is subsequently published must be deposited in either the final version or the final post-review version.
