convention used

In the book it says that in the original convention, the electric dipole is represented by an arrow that points towards the negative partial charge, but then continues to say that the book will use the modern convention, where the electric dipole is represented by an arrow that points to the positive charge. Our notes say that the dipole is represented by arrow pointing towards negative, so are we using a different convention than the book?

During class, Dr. Lavelle mentioned that in physics, the dipole arrow points towards the positive dipole, because it relates to the electric field. However, in chemistry, he explained that the arrow will point towards the negative dipole. I'm not sure about the convention used in the book, but the one used in class points toward the negative dipole, so this is what I would use on tests and homework.
