Not all scenarios of literary compilations being reproduced in two-dimensional drawings are equally problematic. Take, for example, a situation involving a compilation comprising five categories of materials with five selected items in each category arranged in a particular way. lt would not be too difficult to make a case for copyright infringement if someone were to come along and draw a diagram with five columns (or circles or other enclosed polygons). each containing the illustrations or descriptions of the five items selected by the original author and ordered in exactly the same way. The elements of selection and arrangement that comprise the authorial expression in the literary compilation--the manner in which the materials were structured, sequenced and organised--have undeniably been reproduced diagrammatically.
