The Biodiversity Histories Collection of the Lee Kong Chian Natural History Museum is the custodian of the Museum’s non-specimen historical materials related to Singapore’s natural history. The Biodiversity Histories Collection has over 100,000 artefacts, with a majority of the artefacts donated by Museum staffs and individuals acquainted to the Museum. These artefacts consist of three sub-collections: the Visual Collection, the Library and Archive Collection, and the Oral History Collection. Within the collection are the 35mm photographic slides (visual), drawings, catalogues and field notebooks that only exist in physical forms, which the Biodiversity Histories unit aim to digitise and make these materials more accessible to a wider group of audience. The overall historical collection is still growing, with thousands of unsorted visual and written materials, and potential candidates who are relevant to the Museum for interview. Through photographs, handwritten notes and records, the collection reveals how scientific knowledge was built and obtained, often through collaboration, long-term observation, and close engagement with landscapes and communities.
