# Summarization

> Conceptual Guide

Summarization involves creating a smaller summary of multiple longer documents. This can be useful for distilling long documents into the core pieces of information.

The recommended way to get started using a summarization chain is:

    from langchain.chains.summarize import load_summarize_chain
    chain = load_summarize_chain(llm, chain_type="map_reduce")
    chain.run(docs)

The following resources exist:

- Summarization Notebook: A notebook walking through how to accomplish this task.
