This isn't a publication with a free disc but an electronic book (DVD-Rom) with a bonus hardback to accompany it. The paper text is pretty much what you might expect from an art book: glossy colour reproductions, a few short essays to introduce Cornell and some brief commentaries on selected works or themes to his work. As such it is a little disappointing, or, at least, nothing very special. The electronic book is the opposite. Packed with much more information than you initially expect, it contains similar introductory material to the book but expands upon the work massively by allowing you to browse Cornell's materials, listen to a wide range of interviews (with experts, curators, gallery owners and friends), take close-up (magnified) views of his box constructions, and, most significantly, it enables movement between these functions with the click of a button. So, although the disc can be navigated by consistently returning to the main screen and attempting to process the information in a fairly linear manner, its real value is that the information relevant to any one work of art, or any particular theme, can be cross-referenced with ease - leading onto new discoveries or areas of interest. For example, having chosen a particular box construction that is of interest you will be able to look at the details in close up (and perhaps also from a number of angles), watch a short film (if there are any moving parts to be displayed), read specific information about the work of art itself, access selected interviews that relate to this work, look at the source materials used in its construction and investigate other works linked by theme, material or subject. In a deliberate attempt to mimic the revealing intricacies of Cornell's best work the electronic book likewise expands outwards from an initial interest to offer new perceptions and perspectives - using modern technology to make lateral connections in keeping with the artwork it displays. The whole package is lovingly put together with an eye for detail (e.g. thoughtfully providing written transcriptions of the interviews on-screen so that as they progress their content can be read as well as heard), and it successfully catalogues Cornell's work whilst also offering a range of insightful opinions and ideas about how he might be understood. In short, a detailed and worthy celebration of the centenary of Cornell's birth that is completely in tune with Cornell's sensibilities.
