The library can be a good place to start looking for information about the company you want to research. There are tools to use, including library databases, to locate case studies quickly as well
You might want to consider starting with databases:
This database contains monographs, major reference works, book digests, conference proceedings, case studies, investment research reports, industry reports, market research reports, country reports, company profiles, SWOT analyses, detailed author profiles and more. Indexing and abstracts for scholarly business journals back as far as 1886 are included.
The ABI/INFORM Collection includes three comprehensive databases: ABI/INFORM Global, ABI/INFORM Trade & Industry, and ABI/INFORM Dateline. Together, they provide access to thousands of full-text journals, dissertations, working papers, and key business and economics publications such as The Economist and MIT Sloan Management Review. The collection also features in-depth country and industry reports, as well as major news sources like The Wall Street Journal. With broad international coverage, the ABI/INFORM Collection offers researchers a global view of companies, industries, and business trends. It also delivers valuable historical context, with content that dates back to the early 1900s.
