Data of temperature and relative humidity in a historic library in Portugal

Abstract

The correct preservation of old and rare books in libraries needs suitable values of temperature and relative humidity. This paper shows the hygrothermal data acquired in a historic library, the Baroque Library, of the University of Coimbra, Portugal, where several old and rare books are stored. The data were acquired during a 6-month monitoring campaign. In particular, in this paper the spatial and temporal variations of these two parameters are analysed. The data presented in the article are related to the research article entitled "A procedure for identifying chemical and biological risks for books in historic libraries based on microclimate analysis" [1].
