There are a wealth of scanned records available nowadays for Korean genealogical research. However, finding indexed and searchable records is a bit more difficult. Fortunately, there have been some recent advancements.
An amazing project on GitHub includes searchable text file versions of some historical Korean records. The project is called “JoSeon MunKwa”: JoseonMunkwa . The project page includes links to the original sources and has downloadable text files in the data directory. The project code attempts to take on difficult tasks that challenge people researching Korean genealogy, such as addressing multiple people with the same name and people with multiple names. The historical record scope includes:
– Annals of the Joseon Dynasty (조선왕조실록) (A.K.A. Veritable Records of the Joseon Dynasty) (183 books covering 472 years of Joseon history kept by the rulers). This history website explores the indexed records in detail: The Veritable Records of the Joseon Dynasty
– Joseon Family Relations (ManSeongDaeDongBo 만성대동보) (A list of prominent people and their clan lineage including founding clan members). Online searchable record: Josean Lineage Network Information System (LNIS) based on the ManSeongDaeDongBo (The Comprehensive collection of family lineage)
