  Much of the references need some work. I believe that references 1-4 be taken down, and inclusion of mainstream articles be included. I agree with Raffel et al, (1998 or 2007). The papers/references to be included (in chronological order) that have shaped PIV (as follows): ** much of the first papers cover the basics ... Adrian, 1991, Particle-imaging techniques for experimental fluid mechanics, Annual Review of Fluid Mechanics Willert and Gharib, 1992, Digital particle image velocimetry, Experiments in Fluids Keane and Adrian, 1992, Theory of cross-correlation analysis in PIV, Meas. Sci. Technol, (good paper - heavily cited) Westerweel, 1994, Efficient detection of spurious vectors, Exp. Fluids, Santiago et al, 1998, A micro particle image velocimetry system, Exp. Fluids (first paper on micro-PIV) Wereley and Meinhart, 2010, Recent advances in Micro-Particle Image Velocimetry, Ann. Rev. Fl. Mech, (very new paper) Fouras et al, 2007, Three-dimensional synchrotron x-ray particle image velocimetry, Journal of Applied Physics (a good paper on X-ray PIV)   Any ideas? Cheers!
