Specific types of sampling
Respondent Driven Sampling. Matthew Salganik. http://www.princeton.edu/~mjs3/rds.shtml This method uses snowball sampling, not to estimate population characteristics, but to estimate characteristics of a network of people in a hidden population (e.g., drug users, etc)
Respondent Driven Sampling http://www.respondentdrivensampling.org/ Douglas Heckathorn, Cornell U. Respondent Driven Sampling is a chain-referral method, or 'snowball' sampling that yields random samples of target populations and provides the means to calculate unbiased estimates of population parameters.

Random and non random sampling
American Association for Public Opinion Research has a bunch of report http://www.aapor.org/Education-Resources/Reports.aspx including one non-Probability Sampling, June 2013. Reviews of different kinds of non probability sampling and when it may be okay to use them.
Sampling, Nonrandom http://www.blackwellreference.com/public/tocnode?id=g9781405131995_chunk_g978140513199524_ss1-1 Andrew Hayes, in International Encyclopedia of Communication. not free, but should be interesting if you can get it.
Non-probability sampling http://www.statcan.gc.ca/edu/power-pouvoir/ch13/nonprob/5214898-eng.htm overview of types and uses, and says non-probability sampling can be used for questionnaire testing and some preliminary studies during the development stage of a survey.
Sample Size
Ahmed, Saifuddin. 2009. Statistical Methods for Sample Surveys http://ocw.jhsph.edu/index.cfm/go/viewCourse/course/StatMethodsForSampleSurveys/coursePage/index/ by See lecture materials, lecture 3 on sample size.
Smith, Richard L. 2010. Basic concepts in statistics. http://www.unc.edu/~rls/s151-2010/s151.html see class 23, standard approach to sample size.
Wikihow has an explanation http://www.wikihow.com/Calculate-Sample-Size
Lots of sample size calculators on line. Here are a few examples
National Statistics Service, Australian Bureau of Statistics http://www.nss.gov.au/nss/home.NSF/pages/Sample+size+calculator includes explanation of what each part is. This assumes a simple random sample.
WHO Step http://www.who.int/chp/steps/resources/sampling/en/ sample size calculator. There is also an explanation of sample size, in Part 2, Section 2, Preparing the Sample http://www.who.int/chp/steps/manual/en/index2.html
