In intellectual property research, secondary sources often offer a good place to start your research. Treatises and hornbooks provide overviews of legal topics and analysis. Government websites (both domestic and international) offer legal information, give practical advice, and provide portals to intellectual property databases. Blogs and news feeds can help keep you current on breaking developments. Lastly, don't neglect law reviews and other periodicals (including scientific and business-oriented ones) that discuss current issues in more depth.
