The British Library has many online catalogues, including more than 20 specialist catalogues.
While most of the Library's holdings can be found in these catalogues, some material is not yet accessible online. Some categories of early printed materials, for example, are only listed in printed catalogues or handlists. Guidance about these is given in the Early Printed Collections.
The Library has published an extensive and diverse range of catalogues of specialist areas of the collections; some of these are available in our Online Shop.
