How do I find a quote in a book quickly?

Last reviewed: October 14, 2026 · Markdown version

Search inside the book itself, using the rarest few words of the quote rather than all of it. If you own the ebook, the reading app's own search does this: Apple Books calls it Search Book. If you do not own it, Google Books has a "Search inside" box on a book's page that can show where a phrase appears even when the book is not readable in full. And if the book is a PDF, the Find command of whatever opens it does the job. Each route is set out below from its vendor's own help page, read today, with the gaps in that help noted section by section.

You do not have the book: Google Books

Google's help for the current Google Books gives the steps under the heading "Search within a book": search for the title, author, ISBN or keywords, click a title, then "Under the title, click Search inside", and in the window that opens use "Search in this book", type your search and click Search (Use the new Google Books, Google Search Help, read 14 October 2026).

How much you see around a match depends on the book. Google's page on its Library Project explains that for a book still in copyright, "you'll still be able to search through the text of the book, but Google Books will only display a few snippets of text to show you where your search term appears". It lists four ways a book can be shown: Full view, Limited preview, Snippet view and No preview available (About the Library Project, Google Search Help, read 14 October 2026). A snippet is often enough to confirm a quote and catch the page it sits on; it is not enough to read the paragraph around it.

An ebook in Apple Books

Apple's reading guide puts in-book search under moving around the book: "Tap the page, tap [the menu button], then tap Search Book. Enter a word, phrase, or page number, then tap a result" (Read books in the Books app on iPhone, iPhone User Guide, read 14 October 2026). The same box takes a page number, which helps when a citation gives you the page but not the words. The guide also says your place is kept when you close the book and that bookmarks are listed under Bookmarks & Highlights, so once you find the quote it is worth bookmarking.

Google Play Books: the help is quiet on this

Google's reading guide for Play Books, in both its Android and web versions, describes changing the font and text size and jumping around with the Contents button, which the Android version says is "To jump to a chapter, bookmark, or note" (Buy & read ebooks, Google Play Help, read 14 October 2026). Neither version of that page describes searching the words inside a book you are reading. We are not saying the app lacks it; we are saying Google's help page does not document it, so look for a search icon in the reading view rather than expecting steps. If your book is a PDF you uploaded yourself, how Play Books handles PDFs covers what Google does say.

A book that is a PDF

A PDF copy, whether you exported it from a store (downloading an ebook as a PDF covers which stores allow it) or scanned it, is searched with the Find command of whatever app opens it, and that command sits in a different place in each app. Searching for a word in a PDF walks through it, Ctrl+F on a phone maps it app by app, and finding a word in a document covers Word, Docs and Pages files.

One catch is common with older books: a PDF made by photographing or scanning pages holds pictures of words, not words, so Find comes back empty although the sentence is plainly on the page. How to check whether a PDF holds text.

Searching for a half-remembered line

These habits are ours, not a vendor's. Quotes travel in slightly wrong forms, so searching the whole sentence often fails on one changed word. Pick the two or three least common words you are sure of, such as a name or an odd verb, and search those. If nothing comes back, try a second fragment from elsewhere in the line. Older editions and translations differ in wording, so a miss in one edition does not mean the quote is not in the book. And a search for "running" may not find "ran", so try the other forms of a key word too.

When the quote could be in any of many PDFs

Every route above searches one book at a time. If you keep a shelf of PDFs, such as course readers, exported ebooks or scanned chapters, and do not know which one holds the line, DocFind searches inside many PDFs at once on iPhone and Android; results show the file, the page, and the surrounding text, and a tap opens that PDF at that exact page with your keywords highlighted. Scanned pages are read on your device and then searched like the rest.

Its limits for this job: it searches PDFs only, so an EPUB or a book inside a reading app is outside it; it reads printed text in scans, not handwriting; and it does no stemming, so searching for "running" won't find "run".
