《容斋随笔·卷三·李太白》
我考察李阳冰作太白《草堂集序》说： 我任当涂县令，太白病重，有草稿一万卷，还没有修订，在床上交给我，让我作序。 
予按李阳冰作太白《草堂集序》云： 阳冰试弦歌于当涂，公疾亟，草稿万卷，手集未修，枕上授简，俾为序。 
I examined Li Yangbing's "Preface to the Collection of Taibai's Grass Hut", which says: When I was the county magistrate of Dangtu, Taibai was seriously ill. He had 10,000 volumes of drafts that had not been revised. He handed them to me on the bed, and asked me to write the preface.
