# Document loader integrations

> Integrate with document loaders using LangChain Python.

Document loaders provide a **standard interface** for reading data from different sources (such as Slack, Notion, or Google Drive) into LangChain’s [Document](https://reference.langchain.com/python/langchain-core/documents/base/Document) format.
This ensures that data can be handled consistently regardless of the source.

All document loaders implement the [`BaseLoader`](https://reference.langchain.com/python/langchain-core/document_loaders/base/BaseLoader) interface.

<Warning>
  Community document loaders are user-contributed and unverified. LangChain does not review or endorse these integrations; use them at your own risk.
</Warning>

## Interface

Each document loader may define its own parameters, but they share a common API:

* `load()` – Loads all documents at once.
* `lazy_load()` – Streams documents lazily, useful for large datasets.

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
from langchain_docling.loader import DoclingLoader

FILE_PATH = "https://arxiv.org/pdf/2408.09869"

loader = DoclingLoader(file_path=FILE_PATH)

# Load all documents
documents = loader.load()

# For large datasets, lazily load documents
for document in loader.lazy_load():
    print(document)
```
