The title of this book in the Hebrew Bible is "The Proverbs of Solomon, the Son of David, King in Israel"(cf. 1:1). The Greek Septuagint called this book "Proverbs of Solomon."The Latin Vulgate named it "The Book of Proverbs."
There is some debate about whether 1:1 is the title of the whole book or just the title of the first section (chs. 1-9). The first view has in its favor the fact that the Hebrew Bible took the verse as the title of the book. According to this view the references to Solomon in 1:1 are an indication that he was the primary author of the proverbs in the book.1
The second view is that 1:1 simply introduces the first major section of the book. The support for this view is that some succeeding sections begin with a similar caption (cf. 10:1; 24:23; 25:1; 30:1; 31:1).2
In either case the book got its title from the proverbs it contains. The whole book is a book of proverbs so the title is appropriate.
"To read straight through a few chapters of Proverbs is like trying to have a conversation with someone who always replies with a one-liner."3
