There has been several 'photography books of the year' type articles published recently. The first that I was aware of is from The Telegraph and features the university's very own Max Houghton.
The Guardian's Sean O'Hagan is not content with one list but has two - the first of which is personal list, the other, published in The Observer, is arranged by genre. Prudence Hone also has a list published by the Guardian.
There are also lists published on the blogs 5b4, Conscientious, and Alec Soth makes a selection on his blog.
PDN has a list in two parts - although only part two seems to be available online.
Photo-eye magazine makes an excellent list each year, but have not yet published one for 2010. Their 2009 list is worth revisiting though.
