Copyright in the networked world: digital legal deposit

Legal deposit is the requirement that particular types of material be deposited with a national library or designated research libraries. US law does not at present include any requirement for the deposit of works that exist solely in the form of Web pages. For digital materials, it makes no sense to write rules for legal deposit based on the medium. Nations and national libraries that ignore legal deposit for digital works will find themselves missing a significant and unrecoverable portion of their cultural heritage.
