There are a lot of misconceptions and mystique surrounding the Talmud. I'd like to take the opportunity to clarify some fundamental aspects, as relates to the discussion here:
The famous "Talmud page" (discussed in the links in the parent comment) was set by a Christian printer in the 16th century.
It emulated a common layout in medieval Christian manuscripts for Christian primary texts and commentaries [0].
The analogy of the Talmud to a hypertext isn't especially apt, IMO. The Talmud indeed extensively cites Bible and Mishnah, and uses lots of technical terms. In this regard, a better analogy is to legal literature (which is what the Talmud in fact is). While being couched as a (fictional) "conversation"/dialogue between rabbis who lived over the course of ~400 years (100 CE to 500 CE).
In fact, Kabbalah (as another commenter mentioned) is a better example of a “hypertext,” since it’s full of recurring symbols that point to different Sefirot and other core concepts.
(By way of credentials: I hold an MA in academic Talmud and Kabbalah, write on these subjects in several venues, and have presented at academic workshops. Over the past two years, I’ve also been developing digital-humanities projects related to this work.)
