# Catalog ## Overview Your Shadow Catalog allows you to keep track of the contracts and events that you're interested in. ## Contract Catalog To add a contract to your Catalog, click the `+` icon next to the contract name. You can add any contract to your Catalog, even if you haven't made any edits to the original deployed version. Adding or removing a contract to your Catalog has no bearing on the modifications you may have made on that contract; it's just a way for you to keep track of things in the web app. Your shadow fork will continue to execute transactions on the version of the contract that was last deployed.

Once you've added a contract to your Catalog, you'll be able to see it in your Contract Catalog tab.

## Event Catalog To add an event to your Catalog, click the `+` icon next to the event name in the Event Schemas tab of a contract page. You can add any event to your Catalog, even if it's not a custom shadow event. Adding or removing an event to your Catalog has no bearing on the modifications you may have made to the event; it's just a way for you to keep track of things in the web app. Your shadow fork will continue to execute transactions on the version of the event that was last deployed.
