Finding Book Title by Plot: A Complete Guide
Somewhere in a Reddit thread, a reader once described a young adult book they'd read years earlier - something about a mysterious cube in a basement that opened into another world. That was the entire memory. No title, no author, no cover. Within hours, someone in the comments named the book on the first try.
That's the strange, useful thing about book-identification communities — somewhere out there, a stranger read the exact same book you did, and remembers exactly the detail you don't.
If you're looking for help generating your own book title once you find it, our book title ideas framework can guide you through the process step by step.
Why This Is Harder Than a Normal Google Search
A typical search engine matches words. Your memory of a book usually isn't words — it's a scene, a feeling, maybe one specific image that stuck. "Girl finds a cube in her basement" returns almost nothing useful on Google, because that phrase probably isn't printed anywhere. The actual book jacket copy uses completely different language.
This is exactly why finding a book title by plot needs a different approach than searching for a book title the normal way. You're not searching for text that exists — you're searching for a memory that exists only in other readers' heads.
Start With a Detailed Description, Not a Vague One
Before you try any tool or community, spend two minutes building what's essentially a profile of the book. The more specific you get, the faster someone (or something) will recognize it. Useful details include:
- Genre and sub-genre — "fantasy" is too broad; "grimdark urban fantasy" narrows things fast
- Roughly when you read it, and if possible, when it was likely published
- The inciting incident — what actually kicked the story off
- Any specific, unusual image or scene that stuck with you
- Details from the ending — book-finding communities generally expect spoilers, since the ending is often the most identifiable part
Where to Actually Search
Reddit: r/whatsthatbook and r/tipofmytongue
These are, honestly, the best resource available for obscure or half-remembered books. r/whatsthatbook has grown to over 320,000 members who specifically enjoy solving exactly this kind of puzzle — childhood books, out-of-print titles, and books with covers nobody else seems to remember are their specialty.
r/tipofmytongue is broader (over 2.6 million members, covering movies, songs, and more), but it works well for books too — tag your post [TOMT][Book] so the right people find it. Both communities move fast; a good, detailed post often gets a correct answer within hours, sometimes minutes.
Goodreads: "What's the Name of That Book???"
This Goodreads group has run for years and has over 120,000 members — slower to respond than Reddit, but often more thorough. One important detail: the group's rules require you to put the genre and plot details directly in your post's title, not just the body text. Vague headers like "Fantasy" or "Help me find this book" get closed by moderators without anyone even reading further, so front-load the useful information.
Library Databases and Catalogs
WorldCat, LibraryThing, and Google Books all let you search using plot keywords and themes rather than an exact title, drawing from real library catalog data. LibraryThing also runs its own "Name That Book" community forum that works similarly to the Goodreads group.
Ask a Librarian
This one gets overlooked constantly. Librarians spend their careers doing exactly this kind of identification work, and many library systems now offer free "ask a librarian" chat services online — you don't need to physically visit to use them.
Comparing Your Options
| Method | Best For | Typical Wait |
|---|---|---|
| r/whatsthatbook | Obscure, childhood, or out-of-print books | Hours |
| r/tipofmytongue | Popular or mainstream books you've simply blanked on | Minutes to hours |
| Goodreads group | Detailed, dedicated searching from experienced readers | Days |
| WorldCat / LibraryThing / Google Books | Self-service keyword searching, no waiting on people | Instant |
| Ask a librarian | Trained professional help, especially for older books | Same day, usually |
If You Only Remember the Cover
Sometimes the plot's fuzzy but a color, a font, or an image on the cover is burned into your memory. In that case, describe the cover itself to r/whatsthatbook rather than the plot — covers are often easier for other readers to place than a vague storyline. Google Lens can also help if you have anything visual to search from, even a rough sketch.
Common Mistakes That Slow You Down
Being too vague. "A book about a girl in a forest" describes thousands of books. "A girl in a forest who discovers her shadow can move independently of her" describes maybe one.
Skipping the genre and details in your post title. On Goodreads especially, this gets your thread closed before anyone even reads it.
Withholding the ending "to avoid spoilers." In these communities, spoilers are expected and often exactly what triggers someone's memory. Holding back the ending usually just slows your own search down.

Frequently Asked Questions
How do I find a book if I only remember the plot?
Write a detailed description covering genre, approximate era, the inciting incident, and any specific memorable scenes, then post it to r/whatsthatbook or the Goodreads "What's the Name of That Book???" group.
What's the best subreddit for finding a lost book?
r/whatsthatbook for books specifically, especially obscure or childhood titles. r/tipofmytongue works well too and covers a broader range of media.
Is there a website specifically for finding books by plot?
WorldCat, Google Books, and LibraryThing all support keyword and theme-based searching rather than requiring an exact title.
How long does it take to get an answer on Reddit?
Often just hours for a detailed, well-written post. Vague posts can sit unanswered far longer, or never get solved at all.
Can I search for a book by its cover instead of the plot?
Yes. Describe the cover's colors, imagery, or design to a community like r/whatsthatbook, or try a reverse image tool like Google Lens if you have anything visual to work from.
Should I include spoilers when asking for help?
Yes. Most book-finding communities expect and even prefer spoilers, since the ending is often the most distinctive, identifiable part of the story.
What if nobody can identify my book?
Try multiple resources at once rather than one at a time, and consider a librarian — trained professionals are often able to identify books that stump even large online communities.
