" Open text is one of a pair of terms popularized by Eco to refer to kinds of interpretative interactions between text and reader. An open text, unlike a closed one such as a work of popular fiction, is not aimed at a specific reader in a specific social context. It is also open in that its theme, structure and language are more complex, less explicit, more "open-ended": what other critics as Barthes in reception theory would call "Indeterminate". The open text constructs the model of its own reader as part of its structural strategy. "
