Is there a place to report issues?

In section 2.9.1 Quaternions, 4th paragraph reads as if it's missing an equation for the second representation of a quaternion:

  A quaternion can be represented as a quadruple [EQ present] or as [EQ missing] , where is an imaginary 3-vector and  is the real part. We will use both representations interchangeably in this section.

This is what it looks like for me:

Nice find!

In general, you can send errata/bugs to authors@pbrt.org, but we got this one. :-)

It looks like an equation that MathJax wasn't happy with. I've got it fixed now and will include that fix in a push to the site in a little bit.

If you want to be listed as something other than "OnACoffeeBreak" in the errata credits, send me an email (matt@pharr.org).

Thanks again!
