The mission of the International Relations Office (IRO) is to increase ALA's presence in the global library community, to implement ALA policies concerning international librarianship, to promote greater understanding of international librarianship and international library issues within ALA, and to manage international library activities on behalf of the ALA.

To accomplish its mission the IRO coordinates ALA activities in support of official ALA delegations to international events such as book fairs and congresses; promotes international library exchanges and partnerships; recruits international librarians to become members of ALA and attend ALA conferences; responds to international inquiries concerning library issues and activities in the United States; serves as a point of contact for ALA's routine communication with international organizations to which ALA belongs, including IFLA; and provides support for the ALA International Relations Committee (IRC) and the International Relations Round Table (IRRT).
