"Bukhari and Muslim having the most reliable chains of narration"!!!
Bukhari book is for near 200 year after Hijra of prophet written by a biased Persian writer.
Jamal Albanna an Egyptian Scholar argues that 653 of the hadiths as written in al-Bukhari and Muslim are incorrect and should not be accepted. The Arabic book is titled The Cleansing of Bukhari and Muslim from useless Hadiths (2008).
Bukhari was an Iranian living in Bukhara city of Old Iran. Bukhari wrote his book based on the book of his teacher Ali Ibn Madini, the Al-ilal book. He paid some money to child of his teacher and the child took the book of teacher without permission and Bukhari copied the book and then went to Khurasan and wrote the book Bukhari. His teacher when informed became sad very much and died.
Bukhari added many weak hadith in his book that many sunni scholars have rejected them.
Near 60 commentary has written about this book and Near 20 sunni scholar have written books on rejecting this book. But still this book is very important for sunni Muslims.
Bukhari has a high stone on his grave.

the problem of sunni tafsirs is they are biased about Imam Ali (sa) and usually censor the facts of Quran about him.
do you know how 13 of the fourteen infallibles were died and why?
http://en.wikipedia.org/wiki/The_Fourteen_Infallibles
how much do you know about Battle of Karbala?
http://www.al-islam.org/short/karbala.htm
any human should know it.
Imam Husain (sa) wanted to send his message by his blood to all humans in all the history. have you received his message?
the Battle of Karbala is not fiction. its real history. Imam Husain (ra) wanted to declare us with his blood that "tehre is two diffrent Islam, one is Islam of Yazid and Umayyids and other is pure Islam"
old Shia Hadith reference books:
http://en.wikipedia.org/wiki/List_of_Shi%27a_books
en.wikipedia.org/wiki/The_Four_Books
en.wikipedia.org/wiki/Kitab_al-Kafi
the Kafi book alone has more hadith than all 6 main sunni hadith books.
http://www.al-islam.org/nahj/ (a collection of sayings of Imam Ali (sa) the 3th infallible and first of 12 Imam of Shia). this book is called brother of Quran.
prophet said: there is no verse in Quran starting with: O believers! unless Ali is their top and their commanders.
www.al-islam.org/sahifa ( a collection of sayings of Imam sajjad (sa) the 5th infallible)
www.al-islam.org/ has near 3000 of best Shia Books.
Shia books do not accept hadith from sahabah who raped, murdered, drank alcohol, vandalized the qur'an, insulted the qur'an and rebelled against the rashidun state.
Shia ahadith are from the Prophet, Ali, Hassan, Hussein, and the sons of Hussein who they consider divinely appointed imams. Sunnis do not consider them poitical leaders but pious, religious figures in history.
Shias are sometimes also called Jaffaris because Imam Muhammad Baqir and Imam Jaffer As-Saddiq had the opportunity to set up a religious school and teach thousands of students during the shift in power in the government so they were not oppressed. So a lot of the ahadith come from them, mainly Imam Jaffer As-Saddiq. Hadiths from Fatima Az-Zahra are also recorded, all sources originate from Ahlul Beyt.
However, no books are 100% "Sahih" and each Hadith is graded from very weak, weak, strong, and very strong so you would need to check the chain of narrators or its grading to see if it is reliable.
