The selection of sources we can full text search is growing but is still limited by publisher permission.
However, the references within those papers, which are obviously from a much wider set of sources, is available to us and now you can search for them, see the demo << HERE >>.
Click on the example on the search form for a usage guide. Feedback appreciated.
Again, full integration into ChemSpider /ChemMantis and addition of other sources is pending (and running all this off one laptop for too long is not advisable).
This makes article metadata for over a million articles searchable in a structured way.
