Via Andrew Sullivan, Eugene over at My Modern Met (see some of Dettmer's other work there):
Using knives, tweezers and surgical tools, Brian Dettmer carves one page at a time. Nothing inside the out-of-date encyclopedias, medical journals, illustration books, or dictionaries is relocated or implanted, only removed.
Dettmer manipulates the pages and spines to form the shape of his sculptures. He also folds, bends, rolls, and stacks multiple books to create completely original sculptural forms.
“My work is a collaboration with the existing material and its past creators and the completed pieces expose new relationships of the book’s internal elements exactly where they have been since their original conception,” he says.
“The richness and depth of the book is universally respected yet often undiscovered as the monopoly of the form and relevance of the information fades over time. The book’s intended function has decreased and the form remains linear in a non-linear world. By altering physical forms of information and shifting preconceived functions, new and unexpected roles emerge.”
Here is an interview with Dettmer and more images.
