This article present the ergodic literature defining its forms of manifestation thus offering the premise of a redefinition of literary aesthetics. Here are defined terms such as: cybertext, hypertext, IF, etc. and their forms of appearance are presented. Ergodic texts are not, in essence, different from literary ones. Intended or not to be literature, they outline a new literature that also requires an innovative approach. This article analyzes several types of ergodic texts, such as: those created in text-generating programs (AS Bulhak, N. Wylde), cyber-author organizations (OULIPO, ALAMO), hypertexts (texts of M Joyce, R. Gibson, S. Moulthrop, S. Jackson, R. Leybov, D. Larsen, R. Kendall etc.), games (MUDs, Adventure, World of Warcraft, Twisty little passage, Ad Verbum, City of Secrets,etc.) and programming languages / programs that generate this type of text (Perl, Flash, Shockwave, TADS, HTML, Stryspace, HyperCard, Talespin, Racter etc.). Ergodic texts represent a redefinition of the concept of literature through innovations realized both at the structural level and at the level of environment, writer-reader and aesthetic perception.
