1913 Webster's Searchable Online Dictionary

Many modern dictionaries will omit definitions of words that are no longer common. A cool resource I found quite a few years ago is the ARTFL Project: 1913 Webster's Revised Unabridged Dictionary. This thing got me through many a Shakespeare paper, and I believe you will find it helpful, especially if your poem falls early in the packet. I'm also adding this to the sidebar for later reference.
