For new writers, or all writers for that matter, a strong library of reference materials is a necessity. We all think that we know how to write, but after struggling for a while, we realize that we are only human. Here are some that I use. There are more, of course, and other writers can turn you on to those which they prefer.
I also have a large number of other references relating to specific types of writing, but the ones above are those that I'll grab whenever I seek clarity on any basic issue with my writing. Other writers may have a more extensive list, but quantity is not important. The key is to have enough reference texts that can answer all specific questions that might arise with your writing. And if you don't mind second-hand books, many of these can be bought on Amazon for next to nothing. So, get going and acquire some of these.
