I need some help from an English expert.
I've got a research paper due and my instructor gave back my rough draft, saying I had a few grammar/punctuation errors in this one section, but I cant find them. Here is the area in which I made the errors:
One researcher noted that Philip K. Dick’s first sale as a writer was of his story “Roog” to The Magazine of Fantasy and Science Fiction in 1952 and his first published story was “Beyond Lies the Wub” in a 1952 issue of Planet Stories (Jensen i).
She implied that there were at least 2 errors in there, but I can't find them, except maybe a comma before and after "Roog".
