Hi guys, I'm in the process of writing my first novel with the intention of self publishing it as an e book on Amazon and Smashwords etc, but I know next to nothing about the legal and technical side of things. I have done a little homework on the subject of formatting and marketing, which I think I can just about handle, but I'm rather unsure of things regarding copyright and ISBNs. Firstly, I do intend to cough up for an ISBN despite Smashwords offering a free one, apparently. The question is: how many do I need? I would like the book to be available internationally, so I'm basically asking if one ISBN per book is all that's needed? I'm sure that is probably a really stupid question. Secondly, I have no idea about copyright whatsoever. I know I can go through official (and very expensive) channels, but is this a must? I obviously want to protect my work, but I have no idea how most self published authors go about this besides what is written on the copyright page of their book... which brings me neatly on to my final question. Thirdly, I intend to use a pen name (well, I would like to). The pen name is essentially my first name and middle name. I don't have a double-barrelled surname or anything like that; I just have a middle name that can also be a surname. On the copyright page of my book where I state that the book is "published by" can I use the pen name or must I give my real name for this purpose? I think that's enough questions for now and I really hope someone can clear these issues up for me. I've tried some of the official websites to get this information, but it's all jargon and not the kind of plain English that I need for this sort of thing to sink in to my thick old head. Thanks in advance.
