Searching NAP Publications
The National Academies Press Web site has
thousands of books that you can read for free. Browse categories to
find books that interest you or use the search engine above. You can also
search within a book to find the information you want.
To find a book by title or ISBN:
- Enter word(s) that are in the title.
Example: sun, storms or surviving cancer
- Enter the complete ISBN of the book
Example: 0309084385 not 0-309-08438-5.

- Enter obvious word(s).
Example: You want information on nutrition. Enter nutrition
instead of food.
- Enter words that probably appear in the
text of the book.
Example: nutrition, diet, weight get more specific results
than diet food.
- Be specific.
Example: folate, niacin, choline get more relevant results
- Using a comma to separate words will
affect your results.
Example: If you enter toxic environment, that phrase will be
searched. If you separate toxic, environment with a comma,
those two words ("environment", "toxic") will be searched separately,
not as a complete phrase.
Searching within a book
This feature allows users to search the entire text in an individual book to find the exact places in the book that word or phrase appears.
There are two places where you can search the text of a book. If you are reading the book online (the "openbook"), the search box is in the upper right hand corner:
If you're looking at the primary page for a book (the catalog page), click the "Table of Contents" tab and then enter your search term in the search box at the top:
Tips for searching inside a book:
- Enter words that probably appear in
the book in the "Search this Book" box.
Example: reading difficulties or toxic waste.
- Be specific.
Example: hdl, cholesterol gets more relevant results than fats.

Contents. To the left of each chapter are the number of hits, or times
your word or phrase appears in the chapter.
Select a chapter to see where your word(s) or
phrase(s) are located. Excerpts from the chapter provide context.
