One way of accessing material not available in UCL libraries is to use Library Hub Discover, an online catalogue that gives you access to details of materials kept in many UK national, academic and specialist libraries.
Here are some libraries and archives in London that may be of specific interest, not all of them include their catalogues within Library Hub Discover so you may need to go direct to the library's own catalogue.
If your favourite library is missing from this list, please let us know.
