This post is in response to a comment I got asking about new results in Ramsey theory especially the newer ones.

One thing I would recommend is reading the papers of Ronald Graham on Euclidean Ramsey theory and looking at the bibliographies of these papers and looking at the papers there. His papers are here.

I think there is a preprint on Euclidean Ramsey theory that is submitted. It is a survey on open problems in the field.
