Abstract: Systems and methods for manipulating and archiving web content. A uniform resource locator (URL) associated with a network resource is obtained. A virtual copy of the network resource is rendered by accessing the network resource and associated resources using the URL, where the associated resources include presentation data. A client-side representation of the network resource is stored based on the rendering of the virtual copy of the network resource. At least one irrelevant data pattern in the virtual copy of the network resource is identified. The virtual copy of the network resource is manipulated by applying client-side scripting language code to remove irrelevant data associated with the at least one irrelevant data pattern. One or more linked URLs present in the virtual copy of the network resource are recursively processed.
