The work is in the public domain, then global permission to observe and copy the work is already granted. You can buy a book, read it, sell the book, and then write and sell another book based on the ideas contained in the first book (Baker v Seldon). This is the cornerstone of contemporary copyright law. Or read the book on a shelf of a bookstore where the clerk is asleep. Or borrow the book from the library or any other manner where direct compensation of the author is nowhere to be seen. Copyright is consistently interpreted in alignment with the needs of public learning, both by protecting the authorial incentive as well as protecting the public need for knowledge.
