So I know that I can get the official errata for each book here: http://paizo.com/pathfinderRPG/resources (at least for most of the hardcover rule books) and many people reefer to using the "My Downloads" page to find errata. However I don't own PDF versions of the books (at least not most of them) so the My Downloads page won't be of much use to me and the official errata documents often seem a little out of date -- what happens when there are official errata but a new printing hasn't happened?

My question(s):

Where do I find the most current errata for books that I ONLY have a hardcopy of (no PDF) -- The errata documents found on each book's product page are great and all but I am pretty sure that there have been errata for the APG since the second printing and yet the only document is for the changes between the first and second printing (it even says that it was last updated 5 years ago in 2010) so where do I look for a more recent list of errata for this book (and all the others that I have).

Same question for other books like the player companion line (for instance melee tactics toolboox and the like). I have to believe that there are some rules clarifications that have happened for some of these products as well.

Thanks

This may have been asked and answered but I was unable to find it so here goes:

I am building a Zen Archer and was wondering if at 3rd level when he gains the "zen archery" ability if I must use the wisdom mod if it is less than the dex mod?

thanks
