I intend to initially self-publish my work, although it is unlikely to be in its final draft form at the time of publication. This decision is influenced by time constraints associated with a preregistration copyright that is due in October. In the initial publication, my objective will be to articulate the primary concepts of the book and secure copyright protection for those ideas. The first edition will be made available free of charge to safeguard consumer interests. My inquiry pertains to whether I will be able to present the final revised version of my book to an established publisher, contingent upon sufficient interest. Additionally, when self-publishing, should I opt for one of the lesser-known online platforms while reserving the final revision for Amazon?
Please note: I am not asking for any legal advice with respect to the preregistration copyright I have filed. That would be in violation of forum guidelines.
Publishers most likely won't touch a book that's already been self-published. If you've already released it free of charge, why would anyone buy a copy? If your goal is to go through a publishing house (as opposed to self publishing) then it's not a good idea to self publish first, and would probably preclude it ever getting picked up by a publisher.
What's a pre-registration copyright and why are you messing with it? Wait until it's done and then copyright it, no? Am I missing something?
Unless its a massive massive hit like say Wool or the Martian a publisher won't touch a book that's already been published or self published.
there's info here https://aplegal.com/copyright-preregistration-when-and-why/ i'm not any kind of legal expert but my understanding was that the deadline resulting from preregistration was for registration not publication, so there should be no need to self publish to meet it, just finish it and register the copyright but don't publish it anywhere if you intend to try for a trad deal Ideas can't be copyrighted.
