Hebrew Copyright Dates

Formula: Hebrew number + 1240 = copyright dates

(Note the Jewish calendar year spans parts of two Gregorian years -  
LC constructs the copyright date as 2 years)

Example 1					Example 2

	2	0	0			3	0	0
		4	0				3	0

	5	4	4			7	3	7
544 + 1240 = 1784					737 + 1240 = 1977
544 (1783 or 1784)					737 (1976 or 1977)
