These experiments have led to new insights on polarized parton distribution functions, higher-twist effects, parton-hadron duality and extensions of real photon sum rules. In my talk, I will show a few highlights of the most recent experimental results and then focus on the program planned for CLAS12 and the 12 GeV era. </div><div style="margin: 0px; font-size: 10px; line-height: normal; font-family: Arial;" class="">-/abstract-</div></div><div class=""><br class=""></div></body></html>
