What Are We?

Books and Journals

The library contains about 30,000 volumes of bound periodicals and monographs, plus current print and electronic subscriptions to about 140 periodicals. The areas covered by the library collection are pure and applied mathematics, astrophysics, theoretical particle and mathematical physics and biology. The library adds approximately 150 new books annually to the collection. Its collection of bound periodicals is housed in compact shelving on the lower level of Historical-Social Sciences library, and in off-site storage (pre-1940/1980).

Collected Works

The library specifically collects extensively in the area of collected and selected works volumes in mathematics and physics, which you'll find in the 2nd Floor Landing Stacks across from the main Fuld Hall Library.

Digital Resources

While using the campus network or IAS's OpenVPN, the IAS community has access to the majority of Princeton University's digital subscriptions in mathematics, physics and biology. This includes e-book collections.The Mathematics-Natural Sciences Library has access to Math-Sci Net Online , PROLA, and  the JSTOR. backfiles of multiple core Mathematics journals.

Items At Other Libraries

As a affiliate of the Institute, you and your partner/spouse automatically receive faculty library privileges at the Princeton University Libraries (the most extensive collections are found at the Lewis Library & the Harvey S. Firestone Memorial Library); at the Princeton Theological Seminary's Robert E. Speer Library; and access to IAS's Interlibrary Loan services. See Finding Things at Princeton University and Finding Things At Other Libraries for more. Please note that these services are in flux due to COVID-19 restrictions.

Community Donations

The librarians and the Faculties of all four Schools at the Institute warmly appreciate gifts of books and articles from former and current Members of the Institute.

How Do We Operate?

The MNS Library is, above all, a 'house library'.

Privileges: Borrowing privileges are extended to faculty, members, visitors and staff of the Institute for Advanced Study with a valid IAS ID card.  Visiting scholars may consult books in the library reading room.

We strive to keep our collection accessible to as many members of the community as possible. Therefore borrowed IAS items should not be taken off campus (please keep them in your office, or your apartment); and  must be able to retrieve them if asked for. Please notify the Library Office if you wish to transfer a book you have signed out to another specific member.

Check-Out: Borrowers sign and date two book cards found on the inside back cover of the book, or bound periodical. Books may be signed out after hours, but the cards should always be placed in the location's designated box, to be filed by Library staff.  

Items should be kept in the member's office in plain and accessible view. This allows, in the case of need while the signing member is away, retrieval of the book by library.  The borrower will be notified of this transfer by e-mail.  Due to the COVID-19 Pandemic, we are allowing use of MNS Library books in Member housing.

Returns: All books must be returned before a Member's last day at the Institute; we'll contact you approximately 1-2 weeks prior to that date. If you leave early, please make arrangements to return your books at that time, or find alternate means of returning them.

Renewal: The Library performs an inventory at the end of each academic term (June-July), and requests that all books either be a) returned at that time or b) renewed in person for the following academic terms.

Short-Term Visitors: Visitors and students who have access to office space may also borrow books; or alternately sign items out to the office of their collaborator/sponsor; however, recalls and transfers of items from other Members must be negotiated by the student's Sponsoring Member or Faculty supervisor.

Computer – Photocopier – Scanner: A photocopier and a HP digital scanner are available in the Landing Stacks area.  For catalog searching and other use, the library provides a PC in the main reading room, and 2 Macs in the Current Periodical Room and the East Stack Room.

Finding Things at Princeton University

Searching, Browsing, and Using

Lewis Library

The Lewis Science Library of Princeton University supports research in Astrophysics, Biology, Mathematics, Physics, and other science disciplines. Through an agreement with Lewis, books and periodical articles owned there may be requested through MNS Library staff, either by telephone (x8180/8181);  by e-mail; or by filling out the form found on our web page. Due dates and any use restrictions will be provided upon pickup from Fuld Hall. From Monday-Friday, we will attempt to fulfill requests as quickly as possible. Books borrowed from the University library may also be returned through the Mathematics-Natural Sciences Library.

Engineering, Plasma Physics, and RECAP

MNS Library Staff can also assist you in obtaining select items from the libraries at the Engineering School and the Princeton Plasma Physics Lab, as well as remote items stored by the Research Collection And Preservation (RECAP) off-site library.

Firestone Library

The HS-SS library staff provides multiple services for items location at the Harvey S. Firestone Memorial Library.

Princeton University Library

IAS Members and visitors also receive on-site and digital access to the research collections at Princeton University Library.

In order to obtain a library card, visit the Firestone Library Access Office (located in the main lobby area, open 9AM-5PM Mondays-Fridays), and show:

  •  your IAS ID card, and
  •  a photo ID showing your permanent address.

While in the Access Office, you may also arrange a PU printer account, providing use of any network library printer within the PUL system. 

Currently restricted due to COVID-19.

For digital access to PUL e-journals and databases, you must either connect from a IAS campus computer (; 
or, while  off campus, use a Virtual Private Network (VPN) connection.

Finding Things At Other Libraries

Searching and Using

Both of the Institute's libraries participate in the shared cataloguing system of the Online Computer Library Center (OCLC), giving Institute scholars computerized access to WorldCat. This online catalog searches the holdings of thousands of particpating libraries, and provides the location of  or access method for over 22 million items in multiple formats.

For books and journal articles not accessible through the IAS Libraries or Princeton, all members of the IAS community can  request them through Interlibrary loan (other than from Lewis Library at Princeton University). This is available to faculty, members, visitors and their spouses and companions.  Users can request materials on interlibrary loan by using either the online form from our website or by e-mail or telephone.
