SLO Library

The Sea-Level Office (SLO) Library is located on the sixth floor of Mayantigo Building, the ING's sea-level base. The SLO library is split into a book library and a periodical library. The former one is next to the social area, and the latter one is next to the meeting room and the pigeon holes. There is also a display in the social area containing the latest periodical issues, the latest annual and technical reports, the new acquisitions, preprints adn items withdrawn from the libraries.

The access to the libraries is code-protected. Please contact Javier Méndez (ING librarian) for getting this code. The libraries are open 24 hours everyday. The librarian can assist you in the use of the library from 08:30-17:00 from Monday to Friday. However, it is anticipated that the librarian works at the observatory once per week or two weeks. You can also reach him by phoning 616 464 111 or 922 425 464. His email is
