To cite exact2x2 in publications use:

When using Fisher's exact or Blaker's exact test for 2x2 tables cite:

  Fay MP (2010). Confidence intervals that match Fisher's exact or
  Blaker's exact tests. Biostatistics. 11:373-374

A BibTeX entry for LaTeX users is

  @Article{,
    title = {Confidence intervals that match Fisher's exact or Blaker's exact tests},
    author = {Michael P. Fay},
    journal = {Biostatistics},
    year = {2010},
    volume = {11},
    number = {2},
    pages = {373--374},
  }

When using the exact McNemar's test (paired=TRUE) cite:

  Intervals for Discrete Data. R Journal 2(1):53-58.
