Jeffrey Long, Long Brothers Fine and Rare Books (Seattle, WA)

Jeffrey LongJeffrey Long is Seattle’s oldest “young promising bookseller.” As a teen he began loitering in Seattle’s antiquarian bookshops, acquainting himself with the city’s “people of the book,” booksellers, printers, writers, and litterateurs among them. He also edited the Book Club of Washington’s quarterly journal, and served on the club’s board. University “commencement” was embraced as the start of the lifelong pursuit of knowledge and literary pleasure. He founded Long Brothers Fine and Rare Books in 1996, but until lately the business has been an avocational pursuit; in the interim he raised his family and fulfilled a dreary career in corporate administration. Among books in most fields, Long Brothers' specialties reflect his interests: fine literature, Chinese history and culture, bizarre books, Pacific Northwest history, and underground art movements, including the late-‘70s punk milieu from which he sprang. Intellectual curiosity is a valued attribute at Long Brothers Fine and Rare Books; working with readers and fellow ABAA members who share that quality is the best reward of all.


Ellen Saito, Excelsa Scripta Rare Books (Hastings-on-Hudson, NY)

Ellen SaitoEllen Saito was born in Los Angeles. She attended Barnard in New York where she still resides. In college she fell in love with her husband, philosophy, literature, and art history. She was an impassioned architect, but exited Columbia grad school with an expired diploma. The age of computers was upon us; resistance was futile. Every architect adapted by turning to computer-aided design. As a book collector, Ellen enjoyed herself immensely and realized her true passion was bookselling (Eureka!). She practiced on eBay and was encouraged by the income achieved by low prices and immense turnover which she may never see again. She opened Excelsa Scripta Rare Books. She never dreamed of the honor of joining the ABAA until it was suggested to her by a brilliant mentor, and her gratitude is never-ending. She looks forward to exploring her membership in the ABAA and hopes they will offer more references.



Lewis Cohen, B Street Books (San Mateo, CA)

His current interests/specializations include 18th and early 19th-century art auction catalogues, the polemical pamphlets of the art dealer Jean Baptiste Pierre Lebrun, artists' books and the early catalogues of artists' books, and, finally, Japanese manuscripts and scrolls documenting Commodore Perry's expeditions to Japan.

In the fall of 2019 he was fortunate to have the opportunity to apprentice with a thirteenth-generation bookseller in Tokyo for three months. Yoshi now lives in Brooklyn and is a third-generation Grolier Club member; he is also a long-suffering fan of the soccer club Newcastle United. He personally collects the catalogues issued by the San Francisco bookseller Steven Leiber along with the books and works of the artist Jonathan Monk.
