维克多·雨果曾经说过,世界上威力最强大的东西莫过于一种正在得势的新观念。如果雨果先生有幸再多活一段时间,亲眼目睹信息时代的几十年发展史,那么他也许会改变他的这一看法。那时他也许会说,世界上威力最强大的东西莫过于一种正在得势的专业行话。我们可以非常肯定地认为,“超文本”这一行话的时代已经来临。什么是超文本?甚至连这一概念的最坚定的拥护者,在遇到这个问题时也会嗯嗯哼哼的半天说不出个所以然来。超文本的定义多如牛毛。某个人心目中的超文本在另人看来也许不过就是灵巧的信息检索系统而已。从这个方面来说,超文本有点像色情画——任何人只要一看到它就会知道它是什么,但任何人也无法给色情画作出一个简洁明确的大家都会同意的定义。因此,我们在这里不揣冒昧,大胆地给超文本下这样一个定义:超文本就是比较容易地把各类文本数据单元互相联系起来的一种文本(或一项方法)。超文本中的各种文本数据单

Victor Hugo once said that the most powerful thing in the world is a new concept that is gaining momentum. If Mr Hugo is fortunate enough to live an additional period of time and witness the decades-long history of the information age, he may change his view. At that time, he may say that the most powerful thing in the world is one that is gaining momentum. We can be very sure that the era of “hypertext” jargon has come. What is hypertext? Even the most staunchest advocate of this concept will not be able to speak for a long time in the face of this problem. Hypertext definition of numerous. Hypertext in one’s mind may, to others, be but a clever information retrieval system. In this sense, hypertext is a bit of a pornographic painting - anyone can see what it is by seeing it, but no one can make a concise, straightforward definition that everyone will agree with. Therefore, here we do not presume to presume boldly to define such a text as hypertext: a text (or a method) that makes it easier to relate various types of textual data units to each other.
