From the homepage:
The Fifth Workshop on Human-Computer Interaction and Information Retrieval took place all day on Thursday, October 20th, 2011, at Google’s main campus in Mountain View, California. There was a reception on Wednesday evening before the workshop, which attracted about a hundred participants.
By my count fourteen (14) papers and twenty-eight (28) posters.
Quite a gold mine of material and I look forward to a long weekend with them!
Enjoy!
PS: Interesting that papers from prior conferences only start to be available starting in 2010.
