field notes

thumb|upright=1.4|A page of Robert Henry Gibbs|Robert H. Gibbs Jr.'s field notebook Fieldnotes refer to qualitative notes recorded by scientists or researchers in the course of field research, during or after their observation of a specific organism or phenomenon they are studying. The notes are intended to be read as evidence that gives meaning and aids in the understanding of the phenomenon. Fieldnotes allow researchers to access the subject and record what they observe in an unobtrusive manner.

One major disadvantage of taking fieldnotes is that they are recorded by an observer and are thus subject to (a) memory and (b) possibly, the conscious or unconscious bias of the observer. It is best to record fieldnotes while making observations in the field or immediately after leaving the site to avoid forgetting important details. Some suggest immediately transcribing one's notes from a smaller pocket-sized notebook to something more legible in the evening or as soon as possible. Errors that occur from transcription often outweigh the errors which stem from illegible writing in the actual "field" notebook.
