During the 5,000-year period from -1999 to +3000 (2000 BCE to 3000 CE), Earth will experience 12,064 eclipses of the Moon. The eclipses are distributed as follows: 4,378 penumbral eclipses, 4,207 partial eclipses, and 3,479 total eclipses.The "Five Millennium Catalog of Lunar Eclipses: -1999 to +3000" contains an individual figures and maps for each eclipse showing the geographic regions of visibility for each phase (penumbral, partial, and total). The uncertainty in Earth's rotational period expressed in DT and its impact on the geographic visibility of eclipses in the past and future is discussed.The statistics of the lunar eclipse distribution over 5,000 years are examined in detail. This includes eclipse types by month and by century, eclipse frequency in the calendar year, extremes in eclipse magnitude for all eclipse types, maximum durations of penumbral, partial, and total eclipses, and eclipse duos (two eclipses within 30 days of each other).Finally, the periodicity of lunar eclipses is investigated with particular attention to the Saros cycle. Tables list the start and end dates, number, and type of eclipses of every Saros series in progress during the 5,000-year period covered by the Five Millennium Catalog.The Catalog serves as a supplement to the 2-volume "Five Millennium Canon of Solar Eclipses" which contains a map of every eclipse. The Catalog and the Canon both use the same solar and lunar ephemerides as well as the same value of ?T. This 1-to-1 correspondence between them enhances the value of each.

For 100 years, the Congressional Research Service (CRS) has been charged with providing nonpartisan and authoritative research and analysis to inform the legislative debate in Congress. This has involved a wide range of services, such as written reports on issues and the legislative process, consultations with Members and their staff, seminars on policy and procedural matters, and congressional testimony. The Government and Finance Division at CRS took a step back from its intensive day-to-day service to Congress to analyze important trends in the evolution of the institution-its organization and policymaking process-over the last many decades. Changes in the political landscape, technology, and representational norms have required Congress to evolve as the Nation's most democratic national institution of governance. The essays in this print demonstrate that Congress has been a flexible institution that has changed markedly in recent years in response to the social and political environment.
