It's
copyright, not copywrite. They are the rights to copy, not the copying of writings.
As stated, copying and retransmitting books and publications that don't expressly authorize their copying or retransmitting, is simply illegal. However, you may learn information from a book and write your own words to convey that information.
You may reference material from a book, verbatim, but only in small quantities and you must detail exactly what book and page you are referencing. You should only do this when writing about the information in your own words, and include a reference to give your words authority.
Hope this helps.
