Author signings are an important source of traffic for many small community bookstores, but the new California law discussed in this space last year could make them impractical. The bill requires that retailers provide witnessed certificates of authenticity for signed items of value, which must record extensive information on matters such as the size of the edition and price paid, all on pain of steep penalties. They must also retain the resulting paperwork for seven years and will be subject to bounty-hunting suits by “private attorney general” attorneys. The bill’s sponsor apparently did not realize it would apply to signed books. Now Pacific Legal Foundation is challenging the statute in a lawsuit on behalf of San Francisco’s Book Passage store, co-owned by lawyer Bill Petrocelli. [Anastasia Boden, PLF Blog]
