What follows can only be a skim through selected sources recommended to be interrogated as part of an INS360 analysis. It must be born in mind the potential choices are large (i.e. daunting "multi-stop-shop") some of which can, despite their value, also have non-obvious pitfalls (see 'Caveat Usor: Assessing Differences between Major Chemistry Databases', 2018, PMID 29451740). Since the analysis is likely to need informatics collaborators outside the immediate development team, they may of course have other sources and portal entry points they are particularly familiar with but would have similar coverage. It is convenient to divide sources into open and commercial, ordered approximately by their amount of data.
