I feel obliged to inform you, if you didn't already know, that it's Thomas Jefferson's 266th birthday today.  In honor of the day, I thought I'd direct your attention to a lovely essay I discovered a few weeks ago: "Mr. Jefferson and I share Garden Notes."   The author, in the course of busily planning and recording her own garden activities in an Excel spreadsheet, unearths Jefferson's Garden Book online and rediscovers her fond feelings for TJ. The author might be interested to know that one of my colleagues here at the library has said many a time that, if Jefferson were alive today, he would have LOVED Excel.
