Books seem to lend themselves to experiments in miniaturization--and in marketing. LabNewsOnline reports that Canadian physicists have created a 0.07 x 0.10 mm book with thirty silicon chip pages and letters 40 nanometers high (cost per copy: £10,000). Unlike this case, miniature books frequently take the form of scriptures. WNG-GraphiLux markets several scriptures, each inscribed in its entirety on the surface of a single crystal. Available and marketed separately are the entire Greek Bible, the Qur'an in Arabic, and Bhagavad Gita in Sanskrit, which are sold in pendants and other jewelry. The popularity of scriptures as amulets has long fueled the production of tiny scriptures. Miniature Bibles and Qur'ans are now widely marketed on the internet.
