The difference between ISBN, Barcodes, LCCN, & copyright | Which does your self-published book need?

I’ve seen a lot of questions on this on comments on this channel, direct messages that I get from authors, in authors forums, so I am going to set the record straight on these three very different but very important technical aspects of your book. Your ISBN. Your Library of Congress Control Number (LCCN) and your copyright. I’ve done videos on each of these topics individually which I will link to above and down in the description. First, let’s review for US-based authors where to go to get these items: ISBN - Bowker Official Website: https://www.myidentifiers.com/ My Previous Videos on the topic: https://www.youtube.com/watch?v=26p_uWcTdXM https://www.youtube.com/watch?v=IbBSznaGeH8 https://www.youtube.com/watch?v=HOxtMh8Ck5M https://www.youtube.com/watch?v=Bd6ef1UKApY https://www.youtube.com/watch?v=ibL7WRugEyo Barcodes - Multiple Sources Official Website: https://www.myidentifiers.com/ (among others) My Previous Videos on the topic: https://www.youtube.com/watch?v=zfbxXp4lSg4 https://www.youtube.com/watch?v=8KXTxHl22Jw LCCN - Library of Congress Official Website: https://locexternal.servicenowservices.com/sp/?id=landing https://locexternal.servicenowservices.com/auth My Previous Videos on the topic: https://www.youtube.com/watch?v=lAzQP8DXP2Q https://www.youtube.com/watch?v=-a-3_v7P6dI https://www.youtube.com/watch?v=ecEX-RBzYMo https://www.youtube.com/watch?v=IbBSznaGeH8 Copyright - US Copyright Office Official Website: https://eco.copyright.gov/ My Previous Videos on the topic: https://www.youtube.com/watch?v=BMGT6IfEBTE Music from: https://www.bensound.com/ E.R.F.
