Here are the changes from the previous edition:

1. Pottery and earthen-ware industry added. It was completely missing before, unintentionally. This had 1793 observations. We have only one year of data on most of the establishments. Total number of observations is now 104,413.

2. Job content values standardized much further. There are now about 170 standardized jobs for which there are 100 or more wage observations. It is possible to calculate reliable averages of the wages within jobs, and holding year effects constant, to determine which job pay more.

3. Many misspellings corrected.

4. There's more which I'll document later.
