Get Started .... right away! Choose a few areas of interest and note some ideas you are interested in pursuing in these areas. Pick one of the subjects you have noted, and start to read about it right away. Keep at least one other idea in reserve, in case you need to switch topics. You may wish to research more than one topic at least preliminarily as you start. If so, comprehensiveness is still required to ascertain if a writing topic is worthy, so plan accordingly.
Plan Ahead.... You are required to do thorough, scholarly research - this cannot be done in a day or a weekend. Allow yourself enough time to think, find, read, and analyze your research materials before your topic & outline, draft, and final paper are due. Also, plan ahead for any interlibrary loan requests that might be necessary. ILL materials might arrive in a few days or a few weeks. We cannot predict how long it will take to obtain materials from another institution through interlibrary loan.
Keep Track of Your Research. There are many ways to keep track of your research - either electronically on your laptop or PC, or in a paper notebook. However you choose to keep your research log, be sure to keep track of where you've been as you do your research. Remember, you will need to provide complete citations to all of the material you use in your paper - this will be much easier if you have a complete record of the research you've done. Use your research log to make notes about where you found useful materials and how you plan to use them in your paper. The research log is also a good place to note useful sources to return to later, as you refine your paper with additional research and analysis.
Stay Focused on Your Topic. One of the easiest mistakes to make as you begin your research is to find and read interesting materials that are not directly relevant to your work. If you think they may be useful later, make a note of them in your research log. Remain focused on what you need to research at each stage. You can always go back to good sources later.
You may be able to generate ideas from your educational and work experiences. Professors, class discussions, work-related projects, and law librarians can be good sources of ideas. Keep the focus on topics of interest to you.
Reflect on your favorite classes. What issues came up during class discussions that interested you? Talk with professors from your classes, or with a professor who specializes in a field that interests you. He or she will have ideas about whether an issue is ripe for commentary or has been thoroughly addressed in legal literature.
Consider your projects at work or at internships. Did an issue arise that would be a good subject for your note? You could also ask your supervisors at work about emerging issues in practice.
If you have identified a few broader subject areas, the law librarians can teach you how to use databases and current awareness sources to help you narrow your subject area into a more specific topic.
The Bloomberg Law page for Law Reviews and Journals is a helpful place to start as you develop your comment topic. It aggregates links in the Bloomberg database that will help you search subject areas in the Bloomberg practice centers, locate Circuit splits, keep up with the U.S. Supreme Court, research comparative state law charts, and more.
Bloomberg Law's Get Going Get Writing Get Published With Bloomberg Law, describes the comment process and provides guidance for selecting a topic using resources on the Bloomberg site, including U.S. Law Week and other topical law reports. The guide includes Bloomberg Law's organizing system (Workspace), primary law databases, and how to find current court filings in Dockets.
On the Lexis home page, from the Resources tab, follow the Literature & User Guides link to find information about using Lexis to do a preemption check, and other advice about writing for publication.
Commercial legal databases are always adding content for students to help their research, including webinars for topic selection. Westlaw is offering one in August, advertised from its Law Schools homepage. https://lawschool.thomsonreuters.com/
