In the Catholic Lectionary, if I (1) highlight the first reading (2) right click and (3) choose "cited by" -- I get a cited by search on November 8, 2009 and no results. There should be results from other lectionaries.
However, to me it makes no sense - either the liturgical date (Thirty-Second Sunday of Ordinary Time) or the Biblical citation (1 Kings 17:10-16) would make some sense ... or not having the cited by option ...
