# Long description

Figure 7 is designed to visually represent an approach to a literature search which is circular in nature. The figure consists of one main circular process consisting of five stages and from which other arrows flow to indicate things to think about at key points in the circular process. The main circular process consists of five circles placed in a loop with arrows going between them. The top circle has the words ‘1 Plan’ an arrow leads to the next circle with the words ‘ 2 Search’ an arrow leads to the next circle with the words ‘3 Gather’ and an arrow leads to the next circle with the words ‘4 Analyse’ and an arrow goes to the next circle with the words ‘5 Compare’ there is an arrow from this circle back to the circle with the words ‘1 Plan’. This shows an iterative cycle. From circle 2 there is an arrow to a picture of a clipboard which has the words references underneath – a circle goes from this picture to circle 3. Near circle 3 is a picture of some bank paper with the words sources underneath – there is one arrow from this picture to circle 3. There is an arrow from circle 3 to a picture of an open book with the words keep records underneath. There is an arrow from circle 4 to a picture of a piece of paper which is torn with the words discards underneath – an arrow leads from this to the open book with the words keep records underneath. From circle 4 there are a further two arrows – one goes to the picture of a light bulb with the words analysis underneath – an arrow goes form the picture of the light bulb to circle 5. The other arrow from circle 4 goes to a picture of a blank piece of paper with a pencil on it with the words write-up underneath. An arrow also goes form circle 5 to the picture of a blank piece of paper with a pencil on it with the words write-up underneath.
