As a scientific collection is referred to *any systematic collection of objects for the study of nature or of the human history *as well as the institutions, organizations or sub-organizations that build such collections preserve, develop systematically and make accessible and useful. These institutions often examine the collections also itself. Important objects of research collections *in the field of Geology are in particular minerals, rock samples and drilling cores, *in the field of biology in particular plants, fungi, animals, bacteria, archaea and viruses and their remains, *in the field of history for example, wood samples with annual rings, pottery and coins not only for the study of these objects themselves, but also e.g. to determine the age of finds during excavations or ice cores and cores of sediments in lakes for the study of climate history . Important goals of these collections are the items collected for research to make tangible and accessible, hold reference objects for comparison purposes as well as the systematization and naming with scientific names of the collected objects (taxonomy) . == Indexing == The indexing of the collections was historically made by directories, catalogs, index cards, today supplemented by or replaced by databases with information such as e.g. scientific description, including picture, name, location, find circumstances, fund age, scientific analysis, phylogenetic relationships, DNA and isotope analysis results, analysis of pollutants, references, condition of the property, owner changes and name changes.〔http://www.dnfs.de/seite/die-sammlungen〕 Many organisations support the indexing and handling of their collections by specialist libraries. 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「Scientific collection」の詳細全文を読む スポンサード リンク
