Gutterdämmerung (twilight of the gutter margins): e‐books and libraries Available to Purchase

Several aspects of the e‐book revolution are reviewed, as well as some related issues confronting libraries. Regardless of format, texts and text‐bearing devices have relationships of mutual dependence, and readers simultaneously experience both. The dominant relationship between texts and text‐bearing devices is shifting from static to dynamic. The e‐book revolution is more about new distribution systems for content, new digital rights management systems, and perhaps an unwitting or inchoate power struggle among the principal interested parties, than it is about the design and diffusion of dedicated reading devices. The e‐book revolution opens up possibilities for new and improved post‐retrieval processing of texts, defined as anything a person can do with a text after it has been retrieved. Librarians need to reassert – especially to the fledgling e‐book industry – the enduring principle of libraries as a social good. The two biggest challenges facing libraries are how to make the transition to an era dominated by dynamic relationships between texts and text‐bearing devices, and how to foster and facilitate robust and complex post‐retrieval processing of texts.
