The IBO Catalogue
The IBO Catalogue is a unified and searchable catalogue of Berlin's published writings, interviews, broadcasts, and recordings (i.e. of lectures, which were not necessarily broadcast), augmented with some of the unpublished material. Where indicated the entries are accompanied by a PDF of the item in question.
IBO Catalogue entries are preceded by a prefix: B. = broadcast/recording; Bib. = publication; I. = interview; T. = translation. Translations take their number from the original publication and are listed under that date: thus Karl Marx (1939) is Bib.24, its translations T.24, and their date 1939.
In his work as Berlin's editor, Henry Hardy compiled a bibliography for personal use. Such was its value that he made it accessible to other scholars through his online Isaiah Berlin Virtual Library (IBVL). Henry has now generously made the bibliography available to Isaiah Berlin Online, and it has become the centrepiece of The IBO Catalogue.
