A large number of solvent selection guides are available in the literature and have been developed in-house by a number of pharmaceutical companies including GlaxoSmithKline, Pfizer (who have also produced a freely-available printable poster), Sanofi and Astra Zeneca.    . The ACS GCI PR has also produced an industry-wide solvent selection guide, which is also available as a free application for mobile phones.
Although there are a number of solvents where strong correlations in classification exist between the different guides, there are a number of discrepancies. The varying needs and priorities of individual businesses will have direct influence over the exact rankings of solvents. The CHEM21 project has undertaken a survey of these guides to compile the data, analyse and understand the differences therein and have subsequently published a combined guide.  
In this video, Helen Sneddon talks us through the general GSK solvent selection guide.
