\begin{definition}[Definition:General Logarithm/Common/Historical Note]
'''Common logarithms''' were developed by {{AuthorRef|Henry Briggs}}, as a direct offshoot of the work of {{AuthorRef|John Napier}}.
After seeing the tables that {{AuthorRef|John Napier|Napier}} published, {{AuthorRef|Henry Briggs|Briggs}} consulted {{AuthorRef|John Napier|Napier}}, and suggested defining them differently, using base $10$.
In $1617$, {{AuthorRef|Henry Briggs|Briggs}} published a set of tables of logarithms of the first $1000$ positive integers.
In $1624$, he published tables of logarithms which included $30 \, 000$ logarithms going up to $14$ decimal places.
Before the advent of cheap means of electronic calculation, '''common logarithms''' were widely used as a technique for performing multiplication.
