Wow, you've found a lot of errors. Also, some yarn manufacturer's websites have correction pages. Also, last year I found an error in a sock book (can't find it now to share). I emailed the publisher, they checked with the author and emailed me back the correction.

It is troubling to know these errors exist because some inexperienced knitters may not have the knowledge or courage to correct them during the project. They may assume they are doing something wrong. "How come this sock isn't turning out like the picture??!!"

I joined another forum, knitter's review, and they regularly post errors they have found. Which got me to looking on my own. Now, whenever I purchase a book of patterns I go online and type (in quotation marks) the name of the book, the plus sign, and the word corrections, and up pops a page with corrections. Just got the Stitchionary I in the mail yesterday, went online and got the corrections already. I think there would be way to many to keep track of here, although it's a nice idea.

I am a new beginner of crocheting and trying to make the beginner crochet pattern of "easy afghan square" pr Sandi Marshall from the About.om crochet site. The two rows that seem to be incorrect are the main stay of the product, which are the rows of 6 and 7 of the pattern. If someone out their could help me out with this pattern problem, i would love to try to make this, hoping to improve my crocheting, especially turning the corner rows correctly on a small project.
Thank you in advance.
