He called his enterprise Project Gutenberg.

他把这个工程叫作古登堡计划。

During the lifetime of Project Gutenberg alone, the average time a book stayed in copyright in America rose from 30 to almost 100 years.

光是在古登堡计划期间，美国书籍的平均版权保护期限从原来的30年上升到了将近100年。

Project Gutenberg books had a frugal look, with their Plain Vanilla ASCII format, which might have been produced on an old typewriter;but then it was content, not form, that mattered to Mr Hart.

古登堡计划里的书其貌不扬，用最普通的ASCII编码形式打成的文本，看上去无法分辨是否由老打字机做出来的。但是对哈特来说重要的是内容，不是形式。
