The South Korean government has been promoting the digitization of archives for several decades now. This is great for stamp collectors, as highly detailed information on South Korean postal and revenue stamps has come to light thanks to the efforts of South Korean archives. If you can read/write (type) Korean, a lot of information can be found.
Sometimes however people working for the National Archives of Korea, the NAK, have created pages on specific subjects or themes, showing what it is they themselves have found while organizing and digitizing all those items. Here is one specific example: posters created by the South Korean government. These posters show a whole range of subjects, such as house building projects, but for philatelists one category is of particular interest: the posters promoting stamp collecting!
