This is a list of archives and research libraries in the United Kingdom and Republic of Ireland. The list is divided into sub-categories to make it easier to find which archives or libraries you are interested in visiting, including cathedral libraries, private archives, and public libraries.

Each entry has a website link, brief description about the types of resources the repository contains, as well as information about what you are required to do before visiting – for example, making an advanced appointment to visit the archive as there might be limited spaces – and how accessible the library or archive is, especially if the particular repository is only open on certain days of the week.

The aim of this list is to showcase the range of archival and library repositories which are accessible to interested members of the public and to researchers.

In addition, you may be interested in the Royal Historical Society’s own archive (at University College London) which specialises in the personal and institutional records of the Society and the wider historical profession, c.1860-2020s.
