In 2019, we recognize the 78th anniversary of the bombing of Pearl Harbor on December 7. National Pearl Harbor Remembrance Day is observed across the nation this day in honor of all those who lost their lives serving this nation at Pearl Harbor. There were more than 3,500 Americans who lost their lives or were wounded on that solemn day in 1941.
DEWEY DECIMAL SYSTEM DAY
Dewey Decimal System Day is observed annually on December 10.
December 10, 1851, is the birthday of Melvil Dewey (1851-1931) inventor of the Dewey Decimal system of library classification.
As the most widely used library classification system, the Dewey Decimal Classification (DDC) or Dewey Decimal System has been in use since 1876 when American Librarian Melvil Dewey developed and established it. Divided into ten main categories, the numerical system arranges mostly non-fiction publications.
