Editing Marginalia (section)

==Value==
Marginalia can add or detract from the value of an [[association copy]] of a book, depending on the author of the marginalia and on the book.

Catherine C. Marshall, doing research on the future of [[user interface]] design, has studied the phenomenon of user annotation of texts. She discovered that in several university departments, students would scour the piles of textbooks at used book dealers for consistently annotated copies. The students had a good appreciation for their predecessors' distillation of knowledge.<sup>[5]</sup><sup>[6]</sup><sup>[7]</sup>
