MRS Online Proceedings Library (OPL) archive consists of over 70,000 articles by some of the most eminent materials scientists who have been associated with the society over the years, including numerous papers by Nobel laureates such as Stoddart, Goodenough, Feringa, Geim, Whittingham, and more. It now represents a lasting resource for the next generations of scholars and researchers. Featuring content that had been missing in the past, and demonstrating increased fidelity of its existing content, this opus is a must-have for any materials science, technology, and engineering library. Proceedings of MRS Meetings have been a staple of materials research libraries since the series started in the early 1980s. In addition to many titles still available in print, the MRS Online Proceedings Library Archive includes more than 100,000 peer-reviewed papers online—proceedings published from Volume 1 through the 2015 MRS Spring Meeting. The Archive is fully searchable and can be sorted and viewed by meeting or topic.
