Treatise Online was first established in 2010 with the purpose of providing scholars and researchers early access to current sections of upcoming volumes of the Treatise on Invertebrate Paleontology. There are currently 108 published articles that will become components of the nine Treatise volumes currently in preparation.
Printing of the hard copy volumes will continue as usual, with the opportunity for updating chapters published in the Treatise Online before going to press.
Treatise Online is complemented by Digital Treatise, an online collection of all 53 previously published volumes of the Treatise on Invertebrate Paleontology, available as downloadable PDF files.
