The work is a specialized, open-access encyclopaedic dictionary with around 8,000 entries that includes terms related to the different legal disciplines, as well as the history of law, biographic summaries of eminent lawyers and legal concepts. Dr. Junceda helped write some of the dictionary entries on administrative law.
