Look Up Information from Different Sites in One Site Collection
Cross-Site Lookup allows you to look up and pull information from any site in a site collection, adds find-as-you-type functionality to your lookup field, and filters items displayed in the lookup field according to a view defined in the source list (the list the information is being looked up from).
Cross-Site Lookup creates relationships among lists between different sites, looking up information from SharePoint lists in other sites.
