E-text

e-text (from "electronic text"; sometimes written as etext) is a general term for any document that is read in digital form, but especially a document that is mainly text. For example, a computer based book of art with minimal text, or a set of photographs or scans of pages, would not usually be called an "E-text". The term is usually synonymous with E-book.

An E-text may be a binary or a plain text file, viewed with any open source or proprietary software. An E-text may have markup or other formatting information, or not.

An E-text may be an electronic edition of a work originally composed or published in other media, or may be created in electronic form originally.
