Houghton is home to rare books and manuscripts, literary and performing arts archives, and more. Here's how to access these primary source materials.

Houghton Library Access

Houghton Library's reading room and exhibition spaces are open to researchers and visitors with Harvard ID or proof of COVID-19 vaccination and booster. We welcome all who wish to use the library’s collections

  • All visitors to Houghton Library age 12 or older will be required to present proof of vaccination and booster, along with a photo ID for those age 17 and older. See the Harvard Library Vaccination Requirement Policy.
  • Masks recommended: Although it is not required, face coverings are recommended inside the library. 
  • Our policies are based on current disease dynamics and federal (including CDC), state, and Harvard guidelines and may be subject to change or reevaluation. Please review the Harvard Library Visitor Access page prior to your visit for up-to-date policies and guidelines, including information on visiting other libraries.
  • If you have any questions about Houghton Library access, please email us at

Things to know

  • Researchers are always welcome to contact the library prior to visiting so that our librarians can assist you in planning your research project.
  • Researchers younger than 14 years old are welcome to use the collections when accompanied by an adult (18+ years of age).  Both children and adults are responsible for adhering to all reading room policies.

Requesting Materials

Requesting Restricted Materials

Most of Houghton Library’s materials can be seen without special arrangement. However, items designated as "Restricted" in the catalog need permission for access.

Usually an item is restricted because it's very fragile or in a special format that requires staff help for its use. In most cases we offer readers the use of a surrogate (microfilm, facsimile or digital copy) of the restricted item with the goal of prolonging the life of the original.

Occasionally a donor or the family of an author whose papers we hold has requested that an item be restricted because of privacy concerns. In both cases, you must request permission from Houghton staff to view restricted material.

To request permission to access restricted materials, place a request through your HOLLIS Special Request account. Include a note that provides the specific reasons that you would like access to the restricted materials and include a prospective date for your visit.

Researchers who request to see restricted materials will receive a reply to their request as soon as possible, generally within two business days.

Requesting Offsite Materials

Requests for material must be placed at least two business days in advance of the scheduled date by 2PM, and include a scheduled visit date.

No more than 6 items per day may be requested from offsite. If you have questions or would like an accommodation, please contact our Public Services Division.

Reading Room Policies

Houghton Library welcomes researchers to our Reading Room to view our collections, which do not circulate outside of the library. The Reading Room is not open for general study purposes.

Here are some things to keep in mind for your visit:

  • Handling guidelines must be conscientiously followed in order to preserve library material for future use. Library staff are always available to provide guidance.
  • Researchers are welcome to bring pencils, laptops, tablets, phones (in silent mode), digital cameras, and other materials to assist in their research.
  • Researchers are welcome to photograph most materials. Some collections may be subject to donor stipulations that limit or prohibit photography. Researchers are asked not to take pictures of the Reading Room itself, other patrons, or library staff. 
  • The library does not permit the use of pens, tripods, scanners, camera flashes, special lighting, or any other equipment that rests directly on collection material or may pose a risk of damage.
  • In order to preserve relative quiet for our researchers, we ask laptop computer and digital camera users to turn off all audible features, if possible.
  • Researchers may bring personal books or papers into the Reading Room only if these items are necessary for their immediate research. Based on the nature of that material, researchers may need to fill out documentation to differentiate their materials from Houghton collections.
  • Houghton Library provides free lockers to store any materials not permitted in the reading room, such as food and drink, bags, outerwear, and writing instruments other than pencils.
  • We offer a number of supplies that may help you in your research, including: pencils, note taking paper, magnifying glasses, tape measures and rulers, a light box, a UV lamp, a transilluminator, collator, CD player, a loaner laptop, a desktop computers, and headphones.
  • Because of the rarity of the material in the collection, Houghton material may not removed from the Reading Room. Researchers must show all books and papers to the Reading Room staff each time they leave the Reading Room to ensure no collection items are among them. If researchers bring strollers into the reading room, please be aware that they will need to be searched by library personnel upon exit from the room.
  • Please be aware that there is a mandatory bag check for all visitors, researchers, and staff at the library exit.
