A tip to practice getting better at searching in a book.

Suppose you know in which chapter you want to find 
a few paragraphs or sentences about a specific subject.

 

Note the chapter's first and last page and 
find the keyword you are looking for in the Index 
at the end of the book within those pages.

Then you can scan the page the Index directs you to. 

 

Very simple, but we forget these simple tips sometimes.

You can get better very fast at this if you practice a little.

Pick a book you have and play with this searching technique.
