m ssundaztood your recent contribution s to are very much appreciated however you did not provide references or sources for your information keeping wikipedia accurate and verifiable is very important and as you might be aware there is currently a drive to improve the quality of wikipedia by encouraging editors to cite the sources they used when adding content if sources are left unreferenced it may count as original research which is not allowed can you provide in the article specific references to any books articles websites or other reliable sources that will allow people to verify the content in the article you can use a citation method listed at inline citations that best suits each article thanks
