Isaac Asimov BCE's

Although, I really only collect trade editions... there comes a time when a BCE will have some value.

Title:Triangle
Author:Isaac Asimov
Year:1961
Publisher: Doubleday / SFBC
Type:OMNIBUS
Edition:1st edition / 1st printing

Notes: Code C13 on page 516 of both the trade and SFBC issues. Both produced from the same print run, but the BCE was released as a May 1961 selection while the trade issue was published 2 June.

Making this edition a "True" first edition.

Another example of a rare BCE is..

Publication: The Foundation Trilogy
Authors: Isaac Asimov
Year: 1963-10-00
Publisher: Doubleday / SFBC
Pages: 227+227+225

Notes:
      • First edition (not stated).
      • No gutter code in earliest printing.
      • Known reprint codes:"19G", "34G", "32H","15K", "44M"



I have another copy of this book showing the gutter code ("32H") tucked in between pages and an example of my 1963 copy with NO code. Only the first printings in 1963 do not have a Gutter Code
