Location alerts (in the book)

 Annoying location alerts

In this case, in the text, in the book, in this passage, here, in the except, in the article, in the author's works, in her poems, in his plays, etc. 

These phrases are almost always unnecessary. 

You do not need to keep giving your reader these annoying little location alerts. You and your reader are literally on the same page. Assume he knows that the words and sentences  you are referring  to come from the text you are talking about.
