There are several actions connected with resource manipulation in Sophie: * Resources are added to a Sophie book by dragging them into the Sophie [wiki:APP_MAIN_WINDOW Main Window]. * Resources dropped onto a page appear on the page and in the [wiki:APP_RESOURCE_LIST_DISPLAY Resources Tab]. * Resources dropped onto the [wiki:APP_RESOURCE_LIST_DISPLAY Resources Tab] are added to resources but do not appear on the pages of the book. Such resources are available for use by dragging them from the library onto a page. * Resources can be added by use of Import File or Link to File in the [wiki:DOCUMENT_FILE_MANAGEMENT File Menu]. Resources added by Link to File appear in the [wiki:APP_RESOURCE_LIST_DISPLAY Resources Tab], but the file is not imported into the Sophie book. * Resources are deleted from a Sophie book by selecting a resource from the [wiki:APP_RESOURCE_LIST_DISPLAY Resources Tab] and pressing delete key.
