1930 book A young man's heart by Cornell Woolrich

I found this neat old book in a desk. I read the first page and feel like i want to read the rest. .other than its a lil dusty! It was published in New York in 1930. It's in pretty good shape for its age. And it was a library book. . Last check out was in '36. Guess it's way over due! My question is how to tell what number of copies a book is. . I have a few other books. Thanks!
