This issue of "Research Library Issues" ("RLI") presents an introduction article and two companion articles, which highlight Net Neutrality. The introduction article, "Why Net Neutrality Matters and What Research Libraries Can Do about It" (Mary Lee Kennedy), explains that the fundamental intent of the open internet is to encourage the free and open exchange of ideas--the very basis of a democratic society. Although the reversal appears imminent, there are efforts to stay or blunt it at the federal and state levels. The Association of Research Libraries (ARL) is part of these efforts, actively advocating for and acting in the interest of an open internet. The two companion pieces focus on why the reversal matters to research libraries, providing current facts and expert opinion from Clifford Lynch, the Coalition for Networked Information's executive director, and Krista Cox, ARL's director of public policy initiatives. Both articles detail the implications for research libraries if the reversal goes into effect and set out options for library leaders and their respective institutions to pursue in securing an open internet in the interests of all who seek to do research and learn: (1) "Practical Consequences of the Elimination of Net Neutrality for the Research & Education Community: A Speculation" (Clifford A. Lynch); and (2) "Implications of the Reversal of Net Neutrality Rules and Next Steps to Protect the Open Internet" (Krista L. Cox).
