Sunnis and Shi'is have different hadith collections.
However, there is some shared material between the collections - after all, the goal is to obtain the teachings of the Prophet (S), and the Prophet (S) was a single person.
Shi'is will generally allow for the use of some hadith from the Sunni books, depending on sourcing, narrator, and so forth. The reverse is much less common (that is, Sunnis do not usually give credence to Shi'i hadith for matters such as jurisprudence).
Shi'is do not give a special place to or automatically accept the sihah al-sittah or "six authentic books" famed in Sunnism.
Shi'is also give equal weight to the narrations from the Imams (A) as they do to narrations from the Prophet (S), on the grounds that the words of the Imams (A) are the teachings of the Prophet (S).
Hope that helps!
