Shadish, W.R., Cook, T.D., & Campbell, D.T. (2002). Experimental and Quasi-Experimental Designs for Generalized Causal Inference. Boston: Houghton-Mifflin.
this is the latest version of the classic Cook and Campbell and Stanley (previous varied author order). Quasi-experimental designs are those that need to rule out plausible rival hypotheses by methods other than random assignment. Quasi-experimental designs include using existing groups as comparison groups (vs control groups), etc. including surveys.
