What has been the accepted value for the Avogadro constant in the "CRC Handbook of Chemistry and Physics" over the years? Some questions about the constant made me curious as to exactly how much the accepted value has changed over the years. I am pretty sure that I learned a rounded value of $6.023\times10^{23}$ about 1970 which would have been around the 50th edition. I know that sometime after that the accepted value rounded to 4 significant figures was $6.022\times10^{23}$. Of course since 2019 the accepted value has been fixed at exactly $6.02214076\times10^{23}$
It would seem that the CRC handbook is a reasonable source for the accepted value of the constant since it has been updated almost yearly.
Please update the table in the answer in the community wiki page with other values
I dislike offsite image links since they disappear over time. So below is Table 1 from andselisk's comment on the question.
The paper itself is behind a firewall and I can't see it.

See Table 1 in Becker, P. History and Progress in the Accurate Determination of the Avogadro Constant. Rep. Prog. Phys. 2001, 64 (12), 1945–2008. DOI: 10.1088/0034-4885/64/12/206. It covers year up to the year 2001 and is going to save a lot of time. – andselisk
