The image above and the last image of the previous page show four marks for | Insertion and Omission |. The descriptions say | Put in element indicated in margin at place shown by caret. | Take out element indicated. | Don’t make change indicated; let it stand as it is. | A line of dots is placed under the element that is to remain as it is. |
The image above shows two marks indicating | Uncertainty |. The descriptions say | Look this up to see whether or not it is correct. | See what has been omitted in proof by comparing with the copy. |
The image above shows two marks for | Abbreviation |. The descriptions say | Substitute full form for abbreviation. | Substitute numerical figures. |
The signs used to indicate changes should always be placed in the margin of the proof-sheets, and only those marks that show what elements are to be changed should be put in or between the lines of the proof-sheets. The marks in the printed lines and the signs in the margin are often joined by a line to show the connection between them. If this is not done, the signs for the corrections in each line are arranged in the margin in the order in which the marks indicating the elements to be changed appear in the printed line, each sign being set off by a line slanting from right to left. How proof is corrected is shown in the following example:
The image above is the first six lines of an example of a corrected proof. The remaining part of this example is an image that takes up the whole of the next page.
The image above is the continuation of the example of a corrected proof.
