The majority of the Library’s holdings are open access. However, our rarer items, including many mentioned throughout this volume, are fragile and cannot take frequent handling. The works listed here should be requested in writing, in advance, to check their availability for consultation. Items may be unavailable for various reasons, so readers should make prior appointments to consult materials from the art, rare books, archive, research and ephemera collections. It is the Library’s policy to provide or create surrogates for consultation wherever possible. We are actively seeking fundraising in support of our ongoing surrogacy, preservation and conservation programmes.
