# Multiple Vector Stores

The example below shows an agent operating with two vector stores built upon different data sources.

The `TextLoader` loads a TXT file, while the `WebBaseLoader` pulls text from webpages into a document format to accessed downstream. The `Chroma` vector stores are created analogous to what we have demonstrated in our [CSV Loader](/examples/csv-loader.mdx) example. Finally, the `VectorStoreRouterAgent` constructs an agent that routes between the vector stores.

Get the TXT file used [here](https://github.com/hwchase17/chat-your-data/blob/master/state_of_the_union.txt).
:::

URL used by the `WebBaseLoader`:

```txt
https://pt.wikipedia.org/wiki/Harry_Potter
```

:::tip
When you build the flow, request information about one of the sources. The agent should be able to use the correct source to generate a response.
