If you have the Mishna by Neusner, this Tosefta is a good study help. You can jump directly from the Mishna to the Tosefta to the place where the Tosefta quotes the Mishna. Where the Tosefta and Mishna have the same text, the text is shown in italics with the reference to the Mishna. This is very helpful since parts of the Mishna are scattered in different chapters of the Tosefta.
