There are relatively few books published on the photography market: a few key titles are listed on the left of this page. It's often helpful to look beyond these to general photography books, books about specific collections, and general art market books as well.
Juliet Hacking's Photography and the Art Market is a key book. See also Jeffrey Boloten's chapter 'The Contemporary Photography Market' in Art Business Today.
In addition to journals dedicated to photography, art market publications such as Art + Auction and the Art Newspaper often contain relevant material about the photography market. It is also worth checking art world email newsletters.

Websites for individual festivals include:
Sales catalogues
Key auction house departments include:
A few Phillips and Sotheby's catalogues are found with the photography books on the top floor.
Many more catalogues from all the auction houses listed above are kept at the National Art Library.
