Chemical Information and Computation 2017 Number One. 253rd ACS National Meeting and Exposition, San Francisco, CA, April 2-6, 2017 I am pleased to announce that my 49th report in this series will be ready for distribution in early August. It starts with the usual news section covering people, awards, and industry news, and recent developments at over 60 organizations in the computational chemistry, cheminformatics, chemical information, and publishing markets. It also has detailed transcripts of technical presentations in ACS symposia on: * cloud computing * text mining and natural language processing * public-private partnerships in drug discovery and data sharing * advances from CAS. In addition, from other meetings, there are two papers on data science, and chemical structure representation of inorganics and mixtures, plus two posters on similarity searching, and estimating predictive uncertainty. Two reports on the US and European ChemAxon user meetings (already available on open access) are appended. Order forms at http://www.warr.com<http://www.warr.com/>.
