# Collections
## Description
A global Liquid object that provides access to all product collections available on a store.
## Availability
- **Global scope**: Accessible from any template
## Usage
### Iterate Over All Collections
Loop through collections to generate a collection listing:
```liquid
{% for collection in collections %}
{{- collection.title | link_to: collection.url }}
{% endfor %}
```
This produces links to each collection on the store.
### Access a Specific Collection by Handle
Reference a particular collection using its handle:
```liquid
{% for product in collections['sale-potions'].products %}
{{- product.title | link_to: product.url }}
{% endfor %}
```
This iterates through products within the specified collection.
