# Find public-domain books on archive.org by subject

**Use case:** 

Searches archive.org’s text collection for books tagged with a subject — science fiction here — ordered by download count, and returns 150 items with title, creators, date, subjects, description, language, download count, size and the item page URL. Change the query to any subject, author or collection to build a reading list or a text corpus. $0.40 per 1,000 items.

## About this Actor

This example demonstrates how to use [Internet Archive API — Search, Metadata & Files](https://apify.com/insight.solutions/internet-archive-api.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/insight.solutions/internet-archive-api.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
