This field may be used to populate a timeline. It accommodates a certain amount of uncertainty, which is why we recommend using it in conjunction with our often-inexact Date original, but too much uncertainty (say, more than a three-decade span of time) will not make it very useful on a timeline either.
Enter the decade as YY[Tens digit]0s.
Do not use an apostrophe between the 0 and the s.
Do not use “Unknown”—just leave the field blank.
1910s; 1920s; 1930s
