Is "et al." acceptable for citations with exactly two authors?
I have a bunch of information from a source, but the authors names are particularly long; is it acceptable (in MLA) to use "et al." for exactly two authors, e.g., > “The Corpus juris not only preserved Roman law for later generations but, after the twelfth century when it came to be known and studied in western Europe, provided inspiration for most European legal systems.” (Lehman et al. 4)
