I do, but 'my library' was scattered all about in different areas.
I searched and searched and put them in one easily accessible spot. I stacked them under my coffee table, which sits in front of my lazy boy in our family room. My computer is also in the family room and with a quick turn of my head, I can look and see them all in a row.
Believe it or not, most of my books have been bought at yard sales and thrift stores.
A few I have won on writer's blogs.
All of my books are not 'how to' books
The Quotable American and the Sears Roebuck and Co. 1909 Catalog comes in handy for writing info.
Kids Say the Darndest Things! is a great reference for children's writers.
The Book of Answers, Will Rogers, Garfield's Big Book of Excellent Excuses, Great Thoughts & Funny Savings are also good for reference.
I write for children, but I also write articles and short stories and a few longer pieces.
That is why I do not just collect books on or about writing for children.
Do you have a writing library? What type of books do you have to help you with your writing?
