　Goishi tea, a post fermented tea, is produced in Otoyo town, Kochi Prefecture, Japan. The aim of the present study was to elucidate the aroma-active components in Goishi tea by aroma extract dilution analysis (AEDA) using gas chromatography-olfactometry (GC-O) and identify the microorganisms involved in the fermentation process to further understand the aroma formation. Based on AEDA in GC-O, profiles of various aromatic compounds in Goishi tea were analyzed. Hexanoic acid had the highest flavor dilution (FD) value, followed by furfural, furaneol, and ethyl furaneol. Three microorganisms, namely, Aspergillus niger, Pichia manshurica, and Lactobacillus plantarum were isolated and identified based on their rDNA sequences. We prepared post fermented tea using these microorganisms, and the aromatic extract from each tea was investigated to assess the relationship between aroma formation and the microorganism. Ethyl furaneol and thiazoline compounds produced by A. niger were detected in post fermented tea. Ester, alcohol, and phenolic compounds including 4-ethylphenol and 4-ethyl-2-methoxyphenol were detected in the tea with P. manshurica. L. plantarum produced organic acids such as hexanoic and butanoic acids and lactone. Thus, all the three strains, A. niger, P. manshurica, and L. plantarum contributed considerably to aroma formation in Goishi tea.

In this text, correspondence in the art library is considered while seeing the publication situation that can be put based on an epoch-making theory of Clive Phillpot of the major figure and the art library member who has the definition of the Artists book established first by various places in editorial Europe and America. The collection situation in the art library is considered while seeing a part of the publication situation that can be put, it proposes the use of the key word that connects the modern art of Japan to the museum, the document pavilion, and the library next, and, in conclusion, the use method is described. The artists' books is adopted Subject Headings of LC and it is used as data of the owning table at the library of various genres and if an original management word is used the library member the user and everyone will be able to draw out all artists' books instantaneously in the museum and the library field of Japan from among the collection of books now.
