Written language is major way scientists, including single case design (SCD) researchers, establish a record of their work and communicate with one another and with practitioners. This chapter describes some of the standards for preparing technical documents and presents suggestions for helping readers acquire and use a scientific writing style. It provides information on reviewing the literature, conducting systematic reviews and meta analyses using Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) procedures, stating research questions, writing research proposals for evaluation by others. Regardless of the reason for conducting research, it starts with learning what has already been studied, which means reviewing the literature. Reviewing literature is an extremely beneficial use of time. Several general steps are involved when reviewing the literature. These include selecting a topic, narrowing that topic, finding the relevant sources, reading and coding relevant reports, sorting the sources with sound information from those with less trustworthy information, and organizing the findings and writing the review.
