Constellation boundaries

[Dog Star]

Was reading an article the other day which stated that the International Astronomical Union redrew the constellation boundaries back in the 1920's sometime to give us the boundaries which we are familiar with today.
My question is - Can anyone provide me with a link or information as to what boundaries or co-ordinates were used previous to this?
Not of Earth shattering importance, I suppose, but I am curious.
Thanks in advance.
