need a private publisher for my book

7. That someone has posted art on the internet is also not relevant

By doing so, they are violating copyright. If you want to do such a book, you would need to get written permission from the current owners of the copyrights for the work, or prove that the art is in the public domain.

Your opinions in the book are your intellectual property, to which you hold all rights. Use of art in a college environment can be construed as Fair Use, but only in the academic sense, and even there, there are strict limits about what you can and can't do. In many/most cases, reputable schools have negotiated exemptions or pay general use royalties to allow people to use material from, say, their library.

I'm sure your project is well done and was created in good faith, but in the end, it's just not allowed, and never has been. In books I have written, when using anything more than a very short quote, I've asked for and obtained the permission in writing (yes, emails are valid) to actually show their work, or quote their words.

Sorry if I seem a little pedantic on it, but as an author, patent holder, IP rights are very important to me, and while I know you weren't planning anything commercial through your work, it's still their property, regardless of who else is abusing that out on the Internet.
