Hieroglyphics: The Writings of Ancient Egypt Hieroglyphics: The Writings of Ancient Egypt Hieroglyphics: The Writings of Ancient Egypt is a primer on Egyptian hieroglyphics by Maria Carmela Betrò, later professor for Egyptology at Pisa University (published in Italian as "Geroglifici" in 1995; English translation 1996). The standard version of analytic Egyptian hieroglyphs is based upon the 26 categories of the Gardiner's Sign List, (about 700 signs). That categorization is still the basic standard.

HD-Rosetta HD-Rosetta High-Density Rosetta (HD-Rosetta) is a permanent data storage device which contains engraved microscopic information on a small nickel plate. Up to 196,000 pages of information can be stored onto the plate using a focused ion beam. The image capacity for an HD-Rosetta disc can range from 10,000 to 100,000 images on a 4096 by 4096 pixel x vs. y plane. Similar to hieroglyphics and microfilm, HD-Rosetta is used for preserving information. Norsam Technologies has made HD-Rosetta extremely durable, compared to most archival data devices. It has an estimated longevity of 10,000 years, and it can withstand a minimum of
