Biographical writings for occasional and devoted events; almanacs and similar, patents, extracts, also if presented in a series. Exhibition catalogues of private galleries, show programs. Publisher catalogues and antiquarian book trade catalogues, without historical and scientific aims. Advertising and book trade catalogues, if they aren’t the only source in a specific domain, for example: stamps, coins and other art object catalogues.
