Figure 11. Wenshi zhuan citations, detail (see fig. 10 ). This text, though obscure, is repeatedly cited in a variety of Shishuo xinyu and Sanguozhi chapters. More

Figure 13. Network of texts cited in Sanguozhi and Shishuo xinyu annotations, without “Standard Histories.” The entire network has been recalculated and redrawn without the influence of citations of “Standard Histories.” Nodes representing chapters from the Wei (green), Wu (blue), and Shu More

Figure 12. Network of texts cited in Sanguozhi and Shishuo xinyu annotations, shaded here to highlight texts from Suishu bibliographic treatise subcategories that use the word Za 雜 (Miscellaneous): green nodes are “Miscellaneous Histories,” blue nodes are “Miscellaneous Accounts More

Figure 1. Citations in Sanguozhi . Purple nodes represent cited texts. Green nodes represent Wei chapters, and orange nodes represent Wu chapters, both grouped together in relatively tight clusters. The blue nodes, representing Shu chapters, are more broadly distributed, as fewer sources More

Figure 2. Sanguozhi citations, Shu cluster detail. While many texts are cited only once per chapter, several local and regional histories like Huayang guozhi and Xiangyang ji 襄陽記 (The Record of Xiangyang) are cited almost exclusively in Shu chapters, while certain texts whose titles More

Figure 3. Shishuo xinyu citations. Source texts are purple nodes, while the two halves of the first volume are light and dark green, those of the second are light and dark blue, and those of the third are light and dark red. Other conventions are as for figure 1 . More

Figure 4. Shishuo xinyu network center detail. Orange nodes represent Shishuo xinyu chapters, and cited texts are purple nodes. Texts cited frequently in multiple Shishuo xinyu chapters appear at the center of the network. Other conventions are as for figure 1 . More
