samples. Formerly housed at the Forestry School of Yale University in New Haven, Connecticut, it was transferred to the U.S. Forest Service's Forest Products Laboratory in 1969. The second largest xylotheque belongs to the Royal Museum of Central Africa in Tervuren, Belgium, with 57,000 samples. The Thünen Institute of Wood Research in Hamburg has more than 37,000 samples. Selected xylotheques Index xylariorum The Index xylariorum is a listing of the world's xylaria. It was conceived of by William Louis Stern (1926– ) who first published the work in 1967. A subsequent work in 1981 was published by the Botanic Garden of the Polish Academy of Sciences as "No. 1" of the series. Stern then published the third revised edition of this work in 1988. Anna H. Lynch and Peter E. Gasson compiled Index Xylariorum 4.1 in 2010, and the International Association of Wood Anatomists updated the list in 2016 under the supervision of Frederic Lens. In addition to the link to the PDF of this document provided in the reference list of this article, Index Xylariorum 4.1 can also be accessed online as a database through the Global Timber Tracking Network website here. Below is a list of the Index xylariorum codes, locations, and institutional names included by Stern in his 1988 Index xylariorum. This list is provided for historic context. In popular culture For documenta 13 in 2012, American artist Mark Dion created a new hexagonal display chamber for the Schildbach Xylotheque at the Natural History Museum in Kassel, Germany. As part of the project, he created six new volumes made of wood from each of the continents (excluding Antarctica).
