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. Wolbach Library is the library for the Center for Astrophysics (CfA).
The staff of Wolbach Library work to provide resources that respond to and anticipate challenges that impact the astrophysics community— to do this library staff participate in local, national, and international collaborations that support scholarly advancement and enable the creation and sharing of new knowledge.
- Conversation: The Wolbach Library will work to foster conversation among members of the community and actively engage in those conversations to provide resources that meet the community’s continually changing and diverse needs.
- Ownership: The Wolbach Library is a shared resource for all members of the astrophysics community. Community members are invited to contribute their ideas about how the Library can develop collections that help meet their scholarly and personal goals.
- Adaptability: The Wolbach Library will maintain a willingness to adapt to the community’s needs and to enable discovery, sharing, and publication of all research artifacts.
- Support: The Wolbach Library will support the community by providing resources that lower technical and social barriers that impact the future of astronomy research.
- Humanity: Astronomy is a human endeavor, and the Wolbach Library sees people as the most valuable resource at the CfA. The Library therefore prioritizes people and astronomers’ human needs when making decisions about our collections, services, and projects.
- 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 scientific advancement through outreach and training programs
These principles and priorities shape the Library's efforts 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 Wolbach Library also acknowledges the historical and on-going influence that racism, sexism, and colonialism have on astronomers and their research. The Library therefore commits to continually evaluating how the Library’s collections, projects, and services can be useful in combating these forms of oppression and violence.

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.
