Errata for back cover and other material not currently found in this repository?

[WesleyDavid]

I purchased the physical book and was reading the back cover material and found a typo that caused me to pause and re-read the sentence a few times. In the 4th paragraph, fifth sentence (but third line as it's printed), we see (emphasis on the typo is mine):

Will you enjoy being a Staff Engineer or you will toil for years to achieve a role that doesn't suit you?

So the proposition is that I'll enjoy being a Staff Engineer, or else I'll toil for years? 😉 I think "...you will..." should be "...will you...".

EDIT: Looks like that sentence can be found here and here and they're both fixed.

Is there a place where I can find the materials on the cover, in the front matter, references, and other locations that aren't in this repository?
