"Considering all that the book has to offer, What's Your Sign for Pizza? would be meaningful for those in the field of interpreting and interpreter education, ASL instructors, and other individuals who have a desire to deepen their understanding of variation and its influence on the evolution of ASL. Readers will gain insight into what constitutes variation, the different types, and potential reasons for why and how variation has developed over the years. Above all, this book gives strong justification for the importance of further research into the area of sociolinguistic variation in ASL."-- "Journal of Deaf Studies and Deaf Education"
