契丹大字
There are no surviving examples of printed texts in the Khitan language, and aside from five example Khitan large characters with Chinese glosses in a book on calligraphy written by Tao Zongyi () during the mid 14th century, there are no Chinese glossaries or dictionaries of Khitan. However, in 2002 a small fragment of a Khitan manuscript with seven Khitan large characters and interlinear glosses in Old Uyghur was identified in the collection of the Berlin-Brandenburg Academy of Sciences and Humanities. Then, in 2010 a manuscript codex (Nova N 176) held at the Institute of Oriental Manuscripts of the Russian Academy of Sciences in Saint Petersburg was identified by Viacheslav Zaytsev as being written in the Khitan large script.
