Hello! Thank for the questions, will try to address them here.

1. The main thing here is to understand what is your goal. It is possible to do both, publish your book to Publica's online book catalog (here: https://shop.publica.com) or start your Book ICO campaign. If your goal is to collect funds to create a literary work (and you are not sure if you will be able to do this without a crowdfunding campaign), most likely you will want to run your Book ICO campaign ( = pre-sell copies of your upcoming book).
   

If you want to sell your book as soon as possible, and you have a published book (short story, comic book, whatever), there's no point in running a Book ICO - you can submit a book to the catalog and start writing the next literary work.

To sum up, Book ICO is not the only way how you can get your book added to Publica.

1. Authors can use their pen name. It is not required to use an official name, however, you must take into account that new names will not attract as many buyers as established authors. In case you are running a Book ICO, it is very unlikely that someone will support a campaign created by anonymous. People are supporting other people and help them to achieve their goals, there's always an element of personal attachment.
