The U.S. Code is an intellectually rich and rewarding puzzle, but piecing it together requires repetitive, mechanical tasks. Repeatedly flipping back and forth to the right page can deter students from reading and learning to parse the statute and regulations. What if we could automate mechanical tasks so that you could focus on the intellectually rewarding aspects of statutory interpretation and analysis? This is the idea behind our innovative electronic statutory supplements. GeniusLex implements features law professors, students, and practitioners have wanted for decades, including automated identification of all defined terms (with previews and links to context-specific definitions), automated cross links between code provisions and regulations, seamless integration of inflation adjustments with the original text of the Code, and rapid offline search by keyword or section number--all for a fraction of the cost of traditional paperback statutory supplements. Popup Definitions The US Code includes thousands of defined terms. It is important for you to know the meaning of each of the defined terms to understand the meaning of the provisions that contain those defined terms. Unfortunately, these terms are not always labeled as defined terms every time they are used. Even in cases where they are labeled as defined terms, you may need to flip back and forth to several locations in the code if you want to understand a certain provision. To solve the problems associated with understanding defined terms, GeniusLex has provided the solution. All you have to do is to click on a defined term and you will be able to view its meaning instantly. Definitions are specifically related to the context in which they are being used; therefore, they do not apply to all sections of the code. For instance, the definition of “property” in Section 317(a) of the Internal Revenue Code is different from its meaning in Section 351 of the same code. GeniusLex automatically recognizes the context in which a definition has been used and connects you to the correct definition if one is provided in the same title. __________ Read more about our terms and privacy policy here: http://www.geniuslex.com/terms http://www.geniuslex.com/privacy
