A xylotheque (from the Greek ''xylon'' for "wood" and "theque" meaning "repository") is a wood collection. A xylotheque is something more than just collection of wood just as a library is more than merely a collection of books. Almost all rather developed countries with worries about their flora have at least one xylotheque with their flora and one with flora from other places in the world. The xylotheque with a largest number of samples is the Samuel James Record Collection formerly housed at the Forestry School of Yale University in New Haven, Connecticut, and was transferred to the U.S. Forest Service, Forest Products Laboratory in 1969, which houses 60,000 samples. The second largest xylotheque belongs to the Royal Museum of Central Africa in Tervuren, Belgium. As of September 2004, it had 57,165 samples. The Thünen Institute of Wood Research in Hamburg has more than 37,000 samples.〔(【引用サイトリンク】url=http://www.ti.bund.de/en/startseite/home/woods-of-the-world-in-the-vti.html )〕 Other important xylotheques are: A xylotheque is useful to understand the scientific and economic value of the existing woods. At the same time, their samples are used to study the xylotomy, physical and mechanical wood properties, such as durability and preservation. The existence of xylotheques has also immediate applications for anyone who needs to make a morphological-visual analysis of wood. These include technicians, specialists and woodworkers, and also those involved in industry and commerce. Even a modest wood collection has value, as each of its samples is a compendium or monography that encloses a vast information. They are very important in museums, schools and universities for didactic and docent value. For example, there is a ludic xylotheque in the Arboretum de Pézanin,with more of 200 samples, whose weight the visitor is able to compare. A xylotheque becomes really interesting and its use is essential as a study tool and a reference to investigations about identification, use and substitution of woods in real state and movable of our cultural patrimony, as well as in preservation and restoration. ==See also== *List of woods *Wood *Timber *Tree *Arboretum *Botanical gardens 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Xylotheque」の詳細全文を読む スポンサード リンク
