Open data
One outcome of his Open Notebook work is the collection of physicochemical properties of organic compounds he was studying. All of this data he made available as Open data under the CCZero license. For example, in 2009 Bradley et al. published their work on making solubility data of organic compounds available as Open data. Later, the melting point data set he collaborated on with Andrew Lang and Antony Williams was published with Figshare. Both data sets were also made available as books via the Lulu.com self-publishing platform.
