The Collaborative International Dictionary of English v.0.48:

AE \[AE]\ or Ae \Ae\
   A diphthong in the Latin language; used also by the Saxon
   writers. It corresponds to the Gr. ai. The Anglo-Saxon short
   [ae] was generally replaced by a, the long [=ae] by e or ee.
   In derivatives from Latin words with ae, it is mostly
   superseded by e. For most words found with this initial
   combination, the reader will therefore search under the
   letter E.
   [1913 Webster]
