There is a great new book due to be published by Wiley this month called Photography after conceptual art. It is edited by Diarmuid Costello and Margaret Iversen and amongst the artists covered are Ed Ruscha, Bernd and Hilla Becher, Douglas Huebler, Mel Bochner, Sherrie Levine, Roni Horn, Thomas Demand, and Jeff Wall. It sounds like a who's who of key photographers, right?
Well, why wait for the book. All the essays included were previously published in a special issue of the journal Art History, which is available online (volume 32, issue 5).
The journal Art History is indexed by Art Full Text and Art Bibliographies Modern (the key visual arts databases), as well as the British Humanities Index and the Arts and Humanities Citation Index. Five issues a year are published.
