A codebook is a regular feature of qualitative research, a list of themes and their definitions that is vital to collaborative approaches to ethnographic research. According to Saldana, A code in qualitative inquiry is most often a word or short phrase that symbolically assigns a summative, salient, essence-capturing, and/or evocative attribute for a portion of language-based or visual data. A 'tag book' serves the same purpose: to help a community of researchers organize multimedia materials by common themes. For many social media, tags are the primary way to search for or to link to online content. In addition, tags don't just enable research; they perform the content of the media we've uploaded. That additional component requires research on the part of the networked anthropologist. For Remixing activity, one will need to apply to their Institutional Review Board (IRB), since they are interviewing someone and placing various contents online for others.
