You can search for articles on supply chains, logistics and major suppliers by searching databases such as ABI/INFORM Collection, Nexis Uni, Factiva and Business Source Complete for contract announcements and related information. Limit by specific subject whenever possible using terms such as 'supply chain management' or a particular industry (e.g. automotive AND supply chain). Some information is also available for pubic companies in their 10K filings. Supplier portal sites for major manufacturers along with "supplier of the year" awards can help build lists of suppliers.
