Catalogue raisonné of lighting units (570), short biographies of the designers, references, chronology of published O-Luce lighting units, bibliography, photo credits, index of names.
Volume 2 presents all the sources and historical evidence on which the catalogue raisonné is based. After a detailed overview of Ostuni's systematics, Biographies introduces the most important of his designers. The main body of the second volume is comprised of the catalogue raisonné, which is divided into four sections: wall lamps, table lamps, floor lamps and ceiling lamps, containing a total of over 560 lamps. Each lighting unit is described with its model number, designer, year of design, materials, dimensions and – in those cases in which they were published – bibliographical details.
Volume 2 also contains a critical chronological overview of those O-Luce lighting units published in specialised literature, magazines and catalogues at the time. A selected bibliography and a comprehensive index of the relevant figures mentioned concludes the second volume.
