After he keyed in The United States Declaration of Independence in 1971, Michael went on in 1972 and typed in a longer text, The United States Bill of Rights, that includes the ten first amendments added in 1789 to the Constitution (dated 1787) and defining the individual rights of the citizens and the distinct powers ot the Federal Government and the States. In 1973, Michael typed in the full text of The United States Constitution.
From one year to the next, disk space was getting larger, by the standards of the time (there was no hard disk yet), so it was possible to plan bigger files. Michael began typing in the Bible, because the individual books of the Bible could be processed separately as different files. He also worked on the collected works of Shakespeare, with one play at a time, and a file for each play. That edition of Shakespeare was never released, due to copyright changes. If Shakespeare's works belong to the public domain, the comments and notes may be copyrighted, depending on the publication date. But other editions belonging to the public domain were posted a few years later.
In parallel, the internet, which was still embryonic in 1971, was born in 1974 with the launching of TCP/IP (Transmission Control Protocol / Internet Protocol). Its rapid expansion started in 1983.
In August 1989, Project Gutenberg celebrated the completion of its 10th eText, The King James Bible.
In 1990, there were 250,000 internet users, and the standard was 360 K disks. In January 1991, Michael keyed in Alice's Adventures in Wonderland, by Lewis Carroll (published in 1865). In July 1991, he typed in Peter Pan, by James M. Barrie (published in 1904). These two worldwide classics of childhood literature each fitted on one disk.
1991 was also the year the web became operational. The first browser, Mosaic, was released in November 1993. As the web was becoming a popular medium, it became easier to circulate eTexts and recruit volunteers. Project Gutenberg gradually got into its stride, with the digitization of one eText per month in 1991, two eTexts per month in 1992, four eTexts per month in 1993 and eight eTexts per month in 1994. In January 1994, Project Gutenberg celebrated its 100th eText by releasing The Complete Works of William Shakespeare. The steady growth went on, with an average of 8 eTexts per month in 1994, 16 eTexts per month in 1995, and 32 eTexts per month in 1996.
