Each specimen cont ains information that can be revisited and reinterpreted\, particularly in the context of recent large-scale digitization\, which has opened new pos sibilities for research across fields such as ecology\, the history of sci ence\, and biogeography.In this talk\, I will introduce the types of infor mation embedded in herbarium specimens and their labels\, and discuss how these data can be used in research. By integrating information on taxonomy \, locality\, time\, and collectors\, specimen data can be analyzed from m ultiple perspectives.I will present several case studies using Taiwanese c ollections. These include analyses of the spatial and temporal distributio n of specimen collection and comparisons with ecological survey data\, as well as attempts to reconstruct the history of botanical exploration based on label information. One example is a large digital dataset developed si nce 2002 to reconstruct early botanical activities in Taiwan. In total\, 5 1\,325 specimens collected before 1948 have been compiled from multiple he rbaria\, including 45\,755 from the National Taiwan University Herbarium ( TAI). By integrating specimen metadata with GIS-based spatial and temporal analyses\, this dataset allows the reconstruction of collecting routes\, geographic focus\, and research priorities of early Japanese botanists.At the same time\, I will address some practical challenges. Errors in digiti zation and data transcription are not uncommon\, and careful verification is necessary when using these data. Despite these limitations\, herbarium databases provide an important foundation for both ecological and historic al studies.Finally\, I will briefly discuss the current status of Taiwanes e plant specimen databases. While domestic databases are becoming more com plete\, many early collections—especially those made before 1928—are s till housed overseas\, particularly in major institutions such as the Univ ersity of Tokyo and the Royal Botanic Gardens\, and have not yet been full y digitized and catalogued. Improving access to these materials will be an important task for future research.\n\n LOCATION:理学部2号館223号室及びZoom END:VEVENT END:VCALENDAR
