OML’s collections are open researchers of all ages. Access is not restricted solely to academics!

Online Research: Users may search for maps and books online. 

  • Important: when searching for maps and books, check the box “show only results with images” to limit the results to works that can be consulted online.

Onsite Research at OML:

Before visiting OML, check out the current open hours for OML’s facilities.

All visitors to OML must check in at the reception desk. Researchers will be asked to register and must agree to abide by the fundamental rules for treating both rare and reference materials.

Rare Collections: Are paged by OML staff. They can be identified online or through OML’s in-house collections management database.

Reference Collections: OML’s extensive reference materials are housed on (mostly) open-access shelves in the main reading room. Some circulate and may be checked out or obtained through interlibrary loan. The reference materials are all catalogued in Ursus, the University of Maine System library catalog. They are housed in several sections:

  • loose facsimiles, kept behind the reception desk (these are not open-access);
  • bound facsimiles, kept on the flat shelving at the rear of the left-hand side of the reading room;
  • bibliographies, housed on the tall shelves on the right-hand side of the reading room;
  • series, housed in the vault manager’s office;
  • journals, housed in the side “corridor” on the left-hand side of the reading room;
  • oversized books, housed on flat-shelving on the left-hand side of the reading room;
  • books and monographs, housed on the flat (oversize) and regular shelves on the left-hand side of the reading room; and
  • older, semi-rare, and less-popular works are stored in the vault (the open-access shelves are limited) and must be paged.
