The greater part of the Peirce Collection, exclusive of the correspondence, was microfilmed in 1963 - 64. Upon completion of the microfilming, errors in cataloguing were discovered. Because any extensive revision of the microfilm was prohibited by the expense involved, the microfilm, apart from a very few changes, was left alone. Asterisks placed before manuscript numbers have called attention to discrepancies between what was filmed and the revised catalogue descriptions, except where an entire manuscript was removed from the folder reserved for it, in which case, for the sake of convenience, the catalogue description and the microfilm correspond.

MS. 1 Six pages added from MS. 1250 (a p. 14 continuing p. 13; pp. 14, 14, 15, 16, 18 of one or more drafts); 1 p. from MS. 525.

MS. 299 A single-page variant added from MS. 1572.

MS. 316a The notebook is missing. It was not filmed.

MS. 397 Six pages (pp. 7-12) added from MS. 950.

MS. 443 Two pages added.

MS. 473 One page (p. 2) overlooked in the microfilming.

MS. 478 One page (p. 8) overlooked in the microfilming.

MS. 514 One section (pp. 9-40) and several unnumbered folded sheets from prior drafts were added to L 231.

MS. 525 One page removed to MS. 1.

MS. 526 Three pages (pp. 2-4 of Paper I) added from MS. 839

MS. 527 Two pages added from fragments.

MS. 536 Two pages added from MS. 839.

MS. 558 One page (p. 15) added from MS. 1572.

MS. 570 Two pages (pp. 2 and 4) were overlooked in the microfilming.

MS. 574 One page added from fragments.

MS. 586 The notebook is missing, but a positive of it was made by Carolyn Eisele so its contents have been preserved.

MS. 595 Pages 23, 30-32, 38 are rejects of MS. 787. These pages, together with the contents of MSS. 804 and 805, yield some consecutive runs and give some idea of the extent of revision in the final draft of MS. 787. See also below notes to MSS. 717 and 787.

MS. 620 A photostat, formerly part of MS. 317, has been placed here.

MS. 693 One page added to Vol. 3; one page added to Vol. 6.

MS. 707 One folded sheet removed to L 340.

MS. 717 Among the fragmentary pages are pp. 2-3, 8, 21-24 and discarded pp. 8 and 24. These pages are from a draft of the Short Logic (MS. 595). Also MS. 1214 contains partial drafts of MS. 595, and MS. 739 contains pp. 30-32 which are continued by pp. 33-34 of MS. 595. It is likely that other parts of the Short Logic have been scattered throughout the section on Logic. See MS. 903 for fragments of other drafts of MS. 717.

MS. 739 Pages 30-32 are continued by pp. 33-34 of the Short Logic (MS. 595).

MS. 748 This MS. was filmed as if it were a single work. Subsequently it was determined that it actually consisted of several different parts which, because of their importance, have been catalogued under MS. numbers 748 a-d.

MS. 764 Seven folded sheets (28 pp.) added to L 231; two folded sheets (8 pp.) added to L 256.

MS. 787 See MSS. 804 and 805 for rejected pages of MS. 787. These pages, together with pages numbered 23, 30-32, and 38 in MS. 595 (which are also rejects from MS. 787), yield some consecutive runs and give some idea of the extent of revision in the final draft of MS. 787. See also MS. 812 for two missing pages (pp. 8-9).

MS. 802 One page added from MS. 1347.

MS. 804 Rejected pages of MS. 787. MS. 805 Rejected pages of MS. 787.

MS. 807 Pages 16-20 continue a letter draft from CSP to Lady Welby, probably of a letter draft of December 14, 1908.

MS. 839 Three pages removed to MS. 526; two pages removed to MS. 536. one page removed to MS. 937; and one page removed to MS. 157.

MS. 881 The final page (p. 100) added from MS. 278.

MS. 896 The single page is part of MS. 339 and has been removed to that place as a14r and inserted between pp. 108 and 109. MS. 339 has been refilmed with the inserted page.

MS. 919 Two pages removed to MS. 922.

MS. 922 Two pages added from MS. 919; five pages added from MS. 964.

APPENDIX II

A CHRONOLOGICAL LISTING OF PEIRCE'S MANUSCRIPTS

The chronological listing includes not only those manuscripts which Peirce himself dated but also those manuscripts which the several editors of Peirce's manuscripts have dated with varying degrees of confidence. For precise information concerning the dates, both Peirce's and the editors', the reader is referred to the manuscript statements themselves. A word of caution: When more than one year is indicated for a manuscript, as in the case of the Logic Notebook (MS. 339), which covers a period of over forty years, the first year alone is noted in the chronology.

APPENDIX III

CROSS-REFERENCE INDEX: BIBLIOGRAPHICAL ENTRIES

Although for many of Peirce's published writings no manuscripts are extant, there are among his papers some which were published in the Collected Papers and elsewhere. The purpose of this index is to enable the reader who has a bibliographical item in mind to determine at a glance whether there is a corresponding catalogue entry. Only catalogue entries which involved some publication either in whole or in part are noted. The principal exception concerns Peirce's drafts of reviews, which, for the most part, are incomplete and fragmentary, although a few of them were published. The bibliographical items are Burks's, supplemented by Fisch's, and the omission of any item means that there is nothing among Peirce's papers corresponding to it.
