Everyone has a tale, and this moving story: Conversation at a Bar Mitzva by Sarah Shapiro might motivate you to read some others. Here are some of the sites, stories and sounds to help remember.
There are the Yad Vashem site, and the US Holocaust Memorial Museums' sites, and the Women in the Holocaust and Holocaust Survivors projects. CANDLES (Children of Auschwitz Nazi Deadly Lab Experiments Survivors) is a museum and site dedicated to the children who survived. And I don't want to ignore the 5 million non-Jews who were also murdered. Nor will I ignore the Holocaust Heroes who risked everything to save their Jewish neighbors and friends.
Please take a little bit of time to remember those killed and to imagine the ignorance and hatred behind the crimes. Read a story, say a prayer.... and never forget.
