Sotomayor's answers to the "Questionnaire for Judicial Nominees" is available on the United States Senate Committee on the Judiciary here. It's 173 pages, not including the numerous appendices. It provides a wealth of information for Sotomayor researchers.
For example, question 11c (page 15 of the Questionnaire) states:
List all conferences, symposia, panels, and continuing legal education events you have attended after having been confirmed to the district court. For each event, provide the dates, a description of the subject matters addressed, the sponsors, and whether any funding was provided to you by the sponsors or other organizations.
Sotomayor provides a thirty page chart of her activities - - - it seems she judged a great number of moot court competitions at NYC area law schools. Another question seeks copies of all "speeches or talks delivered by you, including commencement speeches, remarks, lectures, panel discussions, conferences, political speeches, and question-and-answer sessions." Sotomayor provides these in the appendices, including another chart of her various talks.
Question 13 seeks citations and information about her judicial decisions. There is a voluminous list and details, with one of the more interesting aspects being her choice of the ten "most significant" opinions and her descriptions.
Question 26 provides a window into the nomination process. When asked to "Describe your experience in the entire judicial selection process, from beginning to end (including the circumstances which led to your nomination and the interviews in which you participated) . . . ." Sotomayor responds:
I was contacted by Gregory Craig, White House Counsel, on Monday, April 27, 2009, with respect to the possibility of a future Supreme Court vacancy. Between that date and the present, I have had frequent telephone conversations with Cassandra Butts, Deputy White House Counsel, including near daily phone calls after Justice Souter on May 1, 2009 announced his intention to resign at the end of the current Supreme Court term. On May 14, 2009, I was interviewed in person at my office by Leslie Kiernan, an attorney at Zuckerman Spaeder LLP. I was interviewed by telephone on Saturday, May 16 by Gregory Craig, Cynthia Hogan, Counsel to the Vice President, Ron Klain, Chief of Staff to the Vice President, David Axelrod, Senior Advisor to the President, Daniel Pfeiffer, White House Deputy Communications Director and Cassandra Butts.
