You will need to do a preemption check to make sure that your idea is original. To do this, you should do a thorough search of the legal literature to determine if another author has already published on your topic, using the same analysis as yours.
Start by compiling a list of search terms that will retrieve any articles similar to your proposed comment.
Search for recent law review articles on your topic in the law journal databases on Westlaw and Lexis.
If your proposed comment is based on a case or statute, you should also use Keycite on Westlaw and Shepards on Lexis to find articles analyzing the case or statute.
For finding the most recent law journal articles in a subject area, you might also search in:
Legal Research Index on Westlaw, using the index headings to find articles on your topic, and
Current Index to Legal Periodicals on Westlaw and Hein Online, a weekly index service arranged by subject area.
Find using Databases@Emory
Find using DiscoverE, Databases@Emory, & WorldCat
To find working papers and pending law review articles, search the abstracts in the Legal Scholarship Network, a division of SSRN, and the articles in the bepress Legal Repository.
Academic legal blogs, such as the Legal Theory Blog and the blogs in the Law Professor Blogs Network, sometimes post announcements of new legal scholarship.
