Journal Preemption: Boalt Research Guide
What is a Preemption Check?
Merriam-Webster defines preemption as "taking possession before others." While generally referring to land, the term is appropriately applied in the journal submission context. Journal editors are charged with a duty to publish only articles whose thesis or intellectual contribution has not already been the subject of an earlier "seizure or appropriation." Black's Law Dictionary 1216 (8th ed. 2004).
The following guide provides a variety of resources to aid you in determining if a submission offers a sufficiently original thesis to warrant publication.
Your individual journal will need to make some preliminary decisions about how strictly preemption is to be applied based on the trend in overall quality of the submissions received.
When to Start
You have several options on when to begin your preemption check depending on the nature of your journal's editorial process. Some journals may have a multi-phase selection process where two editors will do a preliminary reading of an article to determine if it meets base-level standards. If the article is deemed of interest, then the article is read and discussed by the entire editorial board. Some journals do their preemption check after the initial read by the two editors and before the final read by the entire board. Other journals may have a single-phase process and do the preemption check after the article is read by the entire board and slated for acceptance. Either way, the preemption check should be completed by the time an offer is made to the author.

- Who is responsible for completing the preemption check?
How to Start
The preemption check can be shared among editors, but is generally done by one person and after a thorough reading of the article.
- What kind of contribution is this article making to the Academy?
An article discussing a newly decided case or novel legal theory is going to require a different kind of preemption check than one exploring an already well-established area of law.
If the author is exploring a novel topic, keyword searching will be more effective. Non-legal literature should be consulted as appropriate (if the author is drawing on economic, business, philosophy, etc.)
Depth/ Nuance in a well established area
If the author is seeking to expand scholarship in a well established area, keyword searching will be less effective, and the editor will need rely more on skimming the relevant literature to determine where and how this author's article fits into the literature. Consulting with the journal's academic/ practicing advisors will be particularly helpful in these instances.
Hopefully, the editor conducting the preemption check has some familiarity with the topic of the article. If you are the lucky editor needing to do a preemption search for an article in an area in which you know nothing, you will need to spend some time gaining basic familiarity with your topic.

- ALR (search lawcat OR Lexis & Westlaw),
- Topical Treatise (search lawcat for ‘keywords' )
Author's previous publications:
Take a quick look at your author's previous publications, especially those from recent years. The author's CV can provide a comprehensive list of previous works depending on when it was last updated. Search for additional books and articles by your author.
Books on topic:
While you are in LawCat and WorldCat, conduct subject searches on your article's topic. You will want to be aware of books or chapters in books covering the same ground. Be aware that you may need to broaden your subject search from what you would use if searching an article database.
The Legal Indexes:
Next, use one or more of the legal indexing databases available to locate articles on topic/ by your author. These indexes assign subject tags to individual articles. Using the subject tags is a more efficient and effective way to locate topical material than searching for words in a title or full text. Accessing the indexes in their native platform provides greater searching flexibility, but some of them may also be searched through Lexis and Westlaw.
- LegalTrac (LRI on Lexis and Westlaw),
- Index to Legal Periodicals (ILP), and
- Index for Foreign Legal Periodicals (IFLP)
- Legal Journals Index (available on Westlaw)
will generally have greater historical depth than the article databases on Lexis and Westlaw, and include more journal titles (especially those that aren't strictly ‘legal' in nature). You can use the subjects and descriptors to link to or search for other similar materials. Note that the indexes are not yet available on WestlawNext or Lexis Advance.
Full-Text Article Databases-
- Lexis (select ‘US Law Reviews and Journals, Combined'; ‘Legal Resource Index'), and
- Westlaw (select JLR-full text & LRI-index)
Don't forget Google Scholar will link you through to most (no promises of all!) of the UCB campus' restricted access databases. Additionally, Google Scholar will link to some working papers available from
but if you have a hot topic, be sure to also check bePress and LSN individually.
- Hein online Law Journal Library database allows you to search the full text, title, author, description, state, country, or date. You can also limit by subject or search within specific journal titles. When retrieving an article, Hein shows you the matching pages and how many times this article was cited by other articles in the Hein database. You can link out to a list of all citing articles. This is one way to trace the evolution of an idea. Be aware that Hein has an embargo period for many of its journals and may not have the most recent issues.
If your author is not solely a legal scholar, you can locate articles using one of the
- Main Campus databases, i.e. Academic Search Complete. The Main Campus subscribes to almost 250 article databases, so you should spend some time perusing the list of available collections.
Some authors advance their central thesis very little from one article to the next. Your journal should develop standards for when an author's contribution is deemed significant enough. This can be a tricky determination, since authors develop an expertise in a particular area of law and thus will usually have written many articles ‘kind of' on topic. Generally, look for are whether whole sections of the article you are considering publishing appear to be lifted from previous articles, and identifying the new contribution (i.e. a new case is discussed).

Using Outside Resources
Using your Journal's academic and professional advisory board can be helpful when working with a novel article or one where you are unsure of the importance of the author's thesis. Your advisory boards are composed of important busy people, so use their time well. BE PREPARED!
Determine the best advisory board member to contact:
Think about your advisors areas of specialization and ask the one most likely to be knowledgeable in the article's subject matter.
Prepare to make contact:
Re-read the article. Write a short summary (500 words or less). Identify questions (3-5) to ask the advisor. Include specific page number references or short abstracts if appropriate.
E-mail or call the advisor, introduce yourself, ask for help. If the advisor is willing to provide guidance, arrange to provide the necessary materials (the abstract, your questions, the complete article) (maybe just an additional e-mail), provide the advisor with a time-frame, set up a meeting to get the advisor's feedback. Express your unending thanks!
When to Stop
It can be hard to know when to stop your research. There is no one-size-fits-all rule. Exercise that fine legal mind you are developing to make a judgment as to whether you have satisfied your duty to make sure the article you are considering for publication has not already been substantially published elsewhere.
