I agree with that. But this is where the blending is going on. How does Anna get into the Polk in HI and WA for '61?

How does Anna get into the Polk in HI and WA for '61?

Good question. I am looking at a Polk directory for 1902. It says copyright 1902. The title says for 1902-1903. And then later, after they describe the data collected, the date shown is June 5, 1902.

So, the data was obviously collected well before then, because it would also take time to prepare the book for printing. And, how long do they spend collecting the data? My guess would be at least six months.
