The membership requirements for the Independent Self-Publishers Alliance are very simple, and there are two classes of membership with equal benefits:

(1) Self-publisher (i.e., author and publisher) of at least one printed book ("pBook") or electronic book ("eBook").

(2) Non-self-publisher who supports self-publishing (such as a designer, editor, publicist, consultant or author of a book or operator of a website that will help self-publishers). 

To prove that you are the publisher of a printed book please send an email to books@ablecomm.com with a link to a bookseller's website that shows you as the author of the book, as well as some means of identifying you or your company as the owner of the ISBN associated with the book.

Because ISBNs are not necessary for eBooks, membership requirements for  people who self-publish eBooks but not pBooks are simpler. Please send an email to books@ablecomm.com with a link to a bookseller's website that shows you as the author of the eBook, as well as some means of identifying you or your company as the publisher.

Books that identfy vanity presses as publishers are not acceptable. The officers of the association have the final say on such determinations.

For a type-2 membership, please send an email with an appropriate link to books@ablecomm.com
