This document summarizes the work of Marie-Laure Ryan and Espen Aarseth on ergodic literature and cybertext. It discusses their concept of "ergodic" works that require effort to experience, unlike traditional narratives. It also covers Matthew Jockers' approach to microanalysis, which uses computational analysis of large text corpora to study literary trends beyond close reading of individual works. Finally, it mentions the work of Aiden and Michel on culturomics and using big data to analyze trends in human culture.
