NSIDC ARC policies support both the mission and the preservation of the materials held by the Resource Office. You can also download the complete Collection Development and Gifts Policies.

Access to Materials

ARC is open to the public and all materials are available for use on site during ARC business hours (8:00 a.m. - 4:30 p.m., Mon. - Fri.).

Borrowing Materials

Employees of NSIDC and the University of Colorado at Boulder are permitted to check out some materials for use outside of ARC. The following policies are applicable to all materials as listed below. If you have any questions or special needs concerning any Resource Center or archives materials, please contact a librarian.

Resource Center Materials

All materials owned by the NSIDC Resource Center circulate for a three-month period, unless otherwise noted in the following policies.

New Acquisitions

New materials circulate for a two-week period. After the first two months, they are available for the normal check-out period, depending upon type of material.


Maps may be borrowed for one week period. Please use the sign-out sheet in room 269 to check-out maps.

Analog Archives Materials

Those materials designated as archival materials do not circulate. Patrons have restricted access to archival materials, which are housed in the Analog Archives, room 269.

Rare, Reserve, and Reference Materials

The NSIDC library owns some rare materials which are either irreplaceable or cost-prohibitive to replace. NSIDC patrons may borrow these items for a period of two weeks. All other patrons have access to the materials in-house.

Materials designated as reference materials do not circulate, but patrons may access them in the library, room 258.

Renewing Materials

All general circulating materials may be renewed 4 times via phone, email, or Instant Message. For further renewals, the patron must bring the items to the library. All renewals are for the same period as the initial loan. See Borrowing Materials above for loan periods for the different material types.

Replacing Lost or Damaged Materials

If a patron has lost or damaged library material, he or she is responsible for the cost of replacing or repairing the item.
