As I have already noted, you should always be conscious of the opportunity to record your fieldwork observations, impressions, and experience. So, you%u0432%u0402%u2122ll be jotting things regularly. After the preliminary notes you take on-the-fly, you should work with them further as soon as you can. Remember, you are processing them. They don%u0432%u0402%u2122t do this by themselves. Fieldnote writing is an interactive, iterative process. You go back and work with and through them. Again, it is leading you toward the interpretations that you must make. Be sure to take time to fill in what may present as %u0432%u0402%u045Agaps%u0432%u0402%u045C in your presentation of things in quickly taken notes. At least initially, you are writing for yourself but ultimately you must represent things so that other peoplecanexperience%u0432%u0402%u201Dthroughyouraccount%u0432%u0402%u201Dwhatyouencountered.

So, that%u0432%u0402%u2122s why you cannot get in the habit of saying %u0432%u0402%u045AOh, I remember the details so I don%u0432%u0402%u2122t need to write them down.%u0432%u0402%u045C Imagine that you%u0432%u0402%u2122re describing things to someone in a letter. You%u0432%u0402%u2122re on a trip and writing home to someone you really care about and want to %u0432%u0402%u045Atell them everything%u0432%u0402%u045C so that they too can see and understand what%u0432%u0402%u2122s going on. So, you need to have an intimate relationship with your notes. They don%u0432%u0402%u2122t %u0432%u0402%u045Aget done%u0432%u0402%u045C so that you can forget about them until I look at them later. Ethnography happens through the fieldnotes. You are taking notes on your notes on your notes. You are in a dialog with your notes and with yourself. Think about the following as you go back through, reflect on, and variously process your notes and thus your participant-observations.
