# Online source verification

You can perform the following source verification tasks online:

- Compare CRF data to source documents—During source verification, the InForm application displays a specialized view of forms.
- Issue queries where necessary—If your review turns up errors or inconsistencies, you can navigate directly from the source verification view of the form to the Queries page, so that you can issue queries.
- Record the results of your review—The source verification view of a form contains checkboxes so you can mark the items and forms that you have verified.
