Charles Sanders Peirce Papers MS Am 1632 (339) Logic notebook, CSP 339

When editing of Peirce’s papers was begun, this manuscript was largely out of proper sequence and was scattered among several files. During editing an attempt was made to arrange the papers in proper sequence, and following that attempt page numbers were assigned to each part. These numbers appear as lightly penciled marks on the upper right corner of each recto.

Subsequent to the above arrangement, some pages were further rearranged in what was believed to be an improved sequence. In so doing, however, no changes were made in the above assigned numbers. The microfilm produced in 1964 reproduced the pages in this order. A check list of the contents of this manuscript was prepared in August 1961 by Don D. Roberts. This check list follows this document. Within it are indicated some of the sequential changes made prior to microfilming.

Prior to digital photography in 2010, the manuscript was collated against the corrected sequence provided in the checklist. Where the foliation needed to be changed, this was done by lightly striking through the first foliation, and writing the new foliation below it.
