This dataset and website contain millions of pages of previously secret documents about toxic substances. They include secret internal memoranda, emails, slides, board minutes, unpublished scientific studies, and expert witness reports -- among other kinds of documents -- that emerged in recent toxic tort litigation.

We’re constantly adding material from lawsuits involving lead, asbestos, silica, and PCBs, among other dangerous substances. Innovations in parallel and cloud computing have made conversion of these documents into machine-readable, searchable text a far faster process than would have been the case just a decade ago.
