Mergers & Acquisitions

Getting Started

Getting Started

This guide is meant to help you find laws and information on Mergers & Acquisition (M&A) issues; the goal is to provide useful (but not exhaustive) resources.   You may also want to review the Library's Guide on Antitrust.

Research requires analysis and synthesis of information, and no one resource will likely provide sufficient information or data on any given topic.

While conducting your research, you may want to explore: 

  • Laws and regulations governing M&A issues

  • Government agencies controlling M&A issues

  • Practice and study aids, i.e., M&A treatises

  • News sources, including blogs

  • Practical and scholarly articles
  • Data on M&A activity, shareholder agreements & more

For many of these databases, you will need your Harvard University ID and PIN.  For others, you may need to register to gain access.  If you have any trouble accessing a database, please contact the library.

Below are a few common texts on M&A law, but you may want to search Hollis+ for more books about Mergers & Aqcuisitions.  If you browse the shelves in Langdell (see call number KF 1655 area for M&A books) and find a book you like, look around it on the shelf.  Books are shelved by subject.


Government Resources

The Federal Trade Commission and the Department of Justice are the top two federal agencies involved in reviewing mergers and acquisitions deals in the US.  Other agencies may also be involved, depending on the industries impacted.

Practice Materials & Study Aids

Westlaw, Lexis, and Bloomberg all have practitioner pages bringing together cases, laws, regulations, and analysis for your research.  See the links on the left side of this page to begin there.  Other practice aides such as treatises, databases, and library resources can be found here.  If you are having trouble finding exactly what you need, or have a question you can't seem to find an answer for, please contact a Research Librarian.
