 Use a staple remover to carefully remove the staples from the magazine. For the old magazines the staples are generally rusty in any case. Removing staples means that the pages can be made to lie completely flat on the scanner, which is critical for a high quality scan. Make sure that you keep the pages in the correct order! Use a staple remover to carefully remove the staples from the magazine. For the old magazines the staples are generally rusty in any case.

 Before you start scanning in earnest, check that the quality of the scan is as high as possible. Spend some time trying various settings to see which works best. Any areas that are not text/pictures should ideally come out white in the scan. Any speckles or colouring reduce the ability to subsequently OCR the documents, as the below examples show. Before you start scanning in earnest, check that the quality of the scan is as high as possible.

 The margins are not even, so take this into account when you are scanning, and shift the pages one way or the other, otherwise you may lose text off the sides. This is primarily an issue for older magazines which were printed on quarto paper, which is wider than A4. Newer ones are A4 and the text should fit on an A4 page regardless. The margins are not even, so take this into account when you are scanning, and shift the pages one way or the other, otherwise you may lose text off the sides.
