# Manage account-level collections
> A collection is a list of items of your choice that can be used as an attribute in rules or cart item filters.
> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).
For example, you can create a collection with several SKUs or email addresses, and whitelist or blacklist them for a given campaign.
Unlike [campaign-level collections](/docs/product/rules/manage-collections.md),
account-level collections are available in the Applications of your choice. They can be
created and managed only by **Admin** users.
We recommend always using an account-level collection instead of duplicating
campaign-level collections to ensure high maintainability and performance in your
deployment.
## List account-level collections
On the leftmost menu, click **Account** > **Tools** > **Collections**.
This page displays the available collections. It contains the following information for
each of them:
| Column | Description |
| ------------ | ---------------------------------------------------------------------------------- |
| ID | Unique number identifying the collection. It can be used for integration purposes. |
| Name | Name and description of the collection. |
| Applications | Number of Applications the collection is connected to. |
