The main functions of the Library are:
- to serve the needs of those in training for ministry in the Church of Ireland
- to assist in the continuing Christian education of clergy and laity
- to act as a reference library for those seeking information about the Church of Ireland
- to provide a repository in which the archives and manuscripts of the Church can be stored, arranged and made available to researchers in a systematic fashion.
The Library does not provide a genealogical research service. Specific details can be checked for a fee but general genealogical research cannot be undertaken by the Library staff.
Researchers who cannot undertake their own research can find a list of professional researchers at www.apgi.ie.
