Ellis valuation = Shortly after Morris’s death, F. S. Ellis, retired bookseller and co-executor of the Morris estate, did an appraisal of Morris’s early books and manuscripts. The chief significance of this document is, as Sydney Cockerell remarked, that “the prices fixed were as near as possible those paid by Morris.” The valuation was later owned by Cockerell, then by Sanford and Helen Berger, and is now in the Huntington Library. It has been transcribed (unfortunately rather inaccurately) in volume 4 of Norman Kelvin’s edition of the Morris correspondence (see Collected Letters above). In the document there are two sequences of foliation, for manuscripts and books respectively, which we cite as a or b (e.g., fol. 22b), and we then provide the item number—if there is one. (Approximately half the titles are not assigned numbers.) We have also recorded any notations by Cockerell in the document.

MS catalogues (1), (2), and (3) = There are three extant manuscript catalogues of Morris’s library that were compiled either by himself or by his daughters under his supervision. All three passed through the hands of Sydney Cockerell, who had them bound by Katharine Adams in 1911. (1) The earliest, which dates from about 1876, is in the handwriting of Morris and his daughter May. It lists thirteen manuscripts and 291 printed books (with the prices that Morris paid for them). It is now at the Yale Center for British Art. — (2) The second catalogue (c. 1890–91) is larger, containing 92 leaves and nearly 1,000 books and manuscripts. Some of the titles (presumably the most valuable) are marked with X’s. This document—mostly compiled by Jenny Morris but with additions by her father—is at the Bridwell Library, Southern Methodist University. — (3) In the Mark Samuels Lasner Collection, University of Delaware Library, is a much briefer (but more beautiful) manuscript, entirely in Morris’ calligraphic hand and with a few illuminated initials, of selected items in his library. It is 16 pages long and probably was produced in about 1890.
