For one amazing week in November, Adobe Bookshop in San Francisco has agreed to allow its estimated 20,000 books to be reclassified by color. Shifting from red to orange to yellow to green, the books will follow the spectrum continuously, changing Adobe from a neighborhood bookshop into a magical libraryâ€”but only for one week ...
This temporary public installation will be assembled by the San Francisco artist Chris Cobb and a staff of volunteers, who will reorder all the books in one night and, when the week is over, return them to their original locations.
