We have studied the electron channeling patterns (ECPs) of both pure a-axis and pure c-axis epitaxial YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} thin films on various substrates. ECPs from three representative a-axis films (on PrBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} buffered LaAlO{sub 3} (001), MgO (001), and SrLaAlO{sub 4} (001)) and three c-axis films (on LaAlO{sub 3} (001), NdGaO{sub 3} (001), and SrTiO{sub 3} (001)) are presented. The differences between both sets of ECPs are discussed and recorded as references for future identifications.
