Eclipse did the distribution for a couple of comics lines (Ken Pierce Books, Claypool) as well as kinda-sorta co-publishing some other books (most of the Acme books listed Eclipse as the ones who “released” the books, but didn’t publish them), but they also would distribute other random books; sometimes mentioned in the indicia and sometimes not.
Footnotes:
* Eclipse is mentioned in the indicia
† Eclipse is not mentioned anywhere in the book, but catherine ⊕ yronwode (the editor-in-chief at Eclipse) lists the book on her web site.
‡ Eclipse isn’t mentioned anywhere, but the book was listed in an “On the Stands” on the inside front cover of another Eclipse book, so the Eclipse connection should be taken with a grain of organic Maldon salt.
