Talk:I savings bonds

Added info about the composite rate never going below zero from this thread: http://www.bogleheads.org/forum/viewtopic.php?t=37463&mrr=1242178234, generic cleanup. Also replaced specific book reference with pointer to Bogleheads' books and authors. More choices for the reader. LadyGeek 02:26, 13 May 2009 (UTC)
