李壬癸的專書《新港文書研究》於 2010年出版以來，最近又發現了四件新港文書是該書所未收的。其中三件即 Steere於 1874年到即今臺南市左鎮區崗仔林所收購的，保存在美國地理學會圖書館檔案的信封中。另外一件也來自臺南左鎮崗仔林的羅姓家族。這四件分別寫於雍正元年（1723）、乾隆 36年（1771）、乾隆 41年（1776）、嘉慶 3年（1798），先後相差 75年，部分內容可以補充專書之不足。筆者把它們都轉寫和解讀出來，並附原件圖版，供學界參考。

Following the publication of the monograph Studies of Sinkang Manuscripts by Li in 2010, four other Sinkang manuscripts have recently been uncovered. Three of them were originally collected by Joseph Steere in January 1874, lately found in an envelope by Robert Michael Jaegar at the American Geographical Society Library, and the fourth one was unearthed in Gongana, Tainan. With the same format and abbreviations as in the monograph, these four manuscripts (dated 1723, 1771, 1776 and 1798, respectively) were transcribed, with interlinear glosses and free translations in both Chinese and English, offering new and precious information. Scanned copies of the manuscripts are also attached herewith for reference.
