At its June 2016 Meeting 139, the DDC Editorial Policy Committee (EPC) approved new historical period numbers in 930-990 for Pakistan, Bangladesh, Syria, Israel, Jordan, Myanmar, Philippines, Ethiopia, Benin, Tanzania, Mauritius, Guatemala, and Guyana. EPC also approved updates to existing historical period numbers for Egypt, Burkina Faso, Central African Republic, Chad, and Democratic Republic of the Congo. Those updates were published in WebDewey at the end of September 2016. Some of the new numbers were timely, e.g., for Philippines:
959.9053 Administration of Rodrigo Duterte, 2016-
Others were overdue, e.g., for Syria:
956.910423 Administration of Bashar al-Assad, 2000-
Between EPC meetings, proposals for updates to historical period numbers are sent to EPC via email. In December 2016, the period notation for the long-reigning king of Thailand was closed, and a new number was published for the reign of the new king:
959.3044 Reign of Bhumibol Adulyadej (Rama IX), 1946-2016
959.3045 Reign of Wachirālongkō̜n (Vajiralongkorn, Rama X), 2016-
In January 2017, new historical period numbers, both sent to EPC via email, were published to WebDewey for the Gambia and the United States. We watched the situation in the Gambia carefully before publishing the new historical period number, because the country was undergoing a constitutional crisis. The new president (Adama Barrow) was sworn into office in a Gambian embassy in Senegal because the previous president (A. J. J. Jammeh) had rejected the election results and wanted to stay in office. However, Jammeh was persuaded to relinquish office by a coalition of military forces from the Economic Community of West African States (ECOWAS), and the new president was able to return home to Gambia. The Dewey update closed off the administration of Jammeh and started a new history period in 2017, with the administration of Adama Barrow given in an including note.
966.51032 Administration of A. J. J. Jammeh, 1994-2017
Including administration of Adama Barrow, 2017-
The new development for the United States closed off the administration of Barack Obama and opened the administration of Donald Trump.
973.932 Administration of Barack Obama, 2009-2017
973.933 Administration of Donald Trump, 2017-
