Astronomical Institutions (AI) Collection: contains historical publications, papers, and objects created by observatories worldwide.
- Along with the Naval Observatory in Washington, DC, Wolbach holds the most complete collection in the United States. Publications and artifacts representing the history of the Smithsonian Astrophysical Observatory and the Harvard College Observatory are also held within the AI Collection and Wolbach's non-ciculating collections. Many of these objects are unique.
International Astronomy/Astrophysics Thesis Collection: a select world wide collection from the 19th century on, cataloged individually and shelved together.
The Astronomy Thesis Collection on Zenodo is also curated by Wolbach Library staff.
Harvard Astronomy Department Dissertations Collection: shelved alphabetically by author.
Papers resulting from the Harvard Astronomy Department Research Tutorials.
The PHaEDRA Collection: collection of early 19th and 20th century notebooks representing the evolution of observation methods and astronomy as a science. The material exemplifies a unique history of women in science as the collection contains over 2,500 logbooks and notebooks produced by the Harvard Computers and other astronomers.
Books and materials in a broad range of subjects: astronomy, physics, chemistry, engineering, computer science, mathematics, etc.

The John G. Wolbach Library combines the collections of the Harvard College Observatory (HCO) and the Smithsonian Astrophysical Observatory (SAO), forming one of the world’s preeminent astronomical collections.
The Center for Astrophysics
Wolbach Library is the library for the Center for Astrophysics (CfA). The CfA consists of the HCO, the SAO, and numerous ground-based and space-based telescopes and observatories. In 1973, the Smithsonian Institution and Harvard University formalized their collaboration as the "Harvard-Smithsonian Center for Astrophysics" to coordinate the related research activities of the two observatories under a single director. Today, the HCO and the SAO retain their separate identities, each responsible to its parent organization, with combined staff in six scientific divisions and the Library (CfA org chart). This partnership between the Smithsonian and Harvard is now known as the Center for Astrophysics | Harvard & Smithsonian.
The Wolbach Library must provide shared resources that respond to the astronomy community's continuously evolving needs— to do this Wolbach staff participate in local, national, and international collaborations that support scholarly advancement and enable the creation and sharing of new knowledge in astronomy.
- Facilitate research about the Universe
- Lower technical and social barriers that negatively impact the astronomy community
- Promote and amplify the astronomy community’s contemporary and historic work
- Develop projects and priorities that challenge Library staff to excel at an international level
- Seek strategic collaborations that sustain Library programs, services, and projects
- Enable open science through outreach and training programs
These priorities shape the Library's services and guide how staff build, organize, manage, house, and preserve collections of physical and digital artifacts. At Wolbach this work is often done in collaboration with the Astrophysics Data System (ADS).

The HCO collection results from the traditional exchange of scholarly works between observatories in the 1800s, and expanded further as commercially published materials became available. The SAO Library dates back to about 1959, when items were selected from the collection of astronomical material in Washington, DC and moved to Cambridge, MA. In 1975, the two libraries, which had been housed in separate parts of the Observatory, were merged into one library. In 1992, the administration of the HCO and SAO collections was merged under one director and staff.
