来自 MystaKull,7 年前amazing! I can't afford legit academic research on the most popular sites that come up in search results so I thought i was resigned to a pop culture self education, lol... I knew there had to be free and legal :P access to something with substance but I am just too ADD with DDG and I get lost in a torrent of queries... so, THANK YOU!
