“Orphan” refers to books in several different ways. Most commonly, it refers to any publication that lacks an ISBN – often due to self-publishing or small press publishing that does not use ISBNs – making identification more challenging. An ISBN allows for easy tracking down in library catalogs and online databases.
An orphan book can be defined as any book without an owner, not part of a series, trilogy, or set. An orphan book often arises due to publishing houses going out of business or books that were never popular, to begin with; its existence may also indicate rejection from either its author or publisher.
Orphan books refer to any book published without copyright notice and has since passed into the public domain; as no one is holding onto its rights and being charged access, such books tend to be digitized and made freely available online for reading purposes.
Finally, an “orphan” book refers to one that has been published without an author name attached – usually due to author anonymity or pseudonymity. Unfortunately, these books can be challenging to sell as potential buyers cannot know if this author fits their reading preferences.
Orphan books provide insight into another culture and person’s life while comforting children who have lost both parents.
