3 次の文章を読んで, あとの各問に答えよ。 (*印の付いている単語·語句には, 本文のあとに [注] がある。) When we go to the library, we read books/*search for and/share information and have a *discussion with others. // Libraries are very convenient places. /The library has a long history of collecting and keeping books. /Books have been an important part of culture. Around 1445 Johann Gutenberg *invented the *printing machine./ Libraries began to collect the hooks *printed by the printing machine, and the number of libraries grew./ Now some libraries have begun to *digitalize a lot of books.

A computer can keep a lót of data/and it can search for the data in a very short time./When the computer has a lot of digitalized data from the books, these data become an important part of culture. / Michael Hart thought that people would use these data as they like, His idea became a *project. /He couldn't digitalize books which had *copyright, so he digitalized books which were *in the public domain and collected them in a computer./ People were able to read the distalized books without *paying any money. Hart named his project “Project Gutenberg," |He thought his project was as important as Gutenberg's printing machine, because the printing machine also spread knowledge 知識てめる all over the world. / Project Gutenberg continues even after Hart died in 2011.
