Theodore Dreiser wrote in very few books, but he did mark books by underlining passages and by placing marks in the margins. The following list of books with underlining and marginalia includes books that have extensive marking throughout, such as Henry Klein's Bankrupting a Great City and Rufus Jones's Finding the Trail of Life, but the list also includes books that have almost no marking, such as Pedro Labarthe's The Son of Two Nations and Johann von Herder's God, Some Conversations. The acquisition numbers that follow each citation "49D-" or "58D-" identify the books within the Dreiser Collection and indicate the year (1949 or 1958) the books arrived at the University of Pennsylvania. Acquisition lists were prepared indicating that only 117 of the more than 1900 books have markings or marginalia. The following list of works with marginalia was compiled by examining the acquisition lists, which indicate works with marginalia and underlining, as well as the actual collection. But as Stephen Brennan has noted, several books, such as Freud's Three Contributions to the Theory of Sex, have no acquisition numbers because they arrived as part of the manuscript collection, so these books are identified by the file number that indicates their place within the manuscript collection.
