Permissions
It is absolutely essential that authors obtain permission to reproduce any published material (figures, schemes, tables or any extract of a text) which does not fall into the public domain, or for which they do not hold the copyright. Permission should be requested by the authors from the copyright holder (usually the Publisher, please refer to the imprint of the individual publications to identify the copyright holder).
Permission is required for:
- Your own works published by other Publishers and for which you did not retain copyright.
- Substantial extracts from anyone's works or a series of works.
- Use of Tables, Graphs, Charts, Schemes, and Artworks if they are unaltered or slightly modified.
- Photographs for which you do not hold the copyright.
Permission is not required for:
- Reconstruction of your own table with data already published elsewhere. Please notice that in this case, you must cite the source of the data in the form of either "Data from..." or "Adapted from...".
- Reasonably short quotes are considered fair use and therefore do not require permission.
- Graphs, Charts, Schemes and Artworks that are completely redrawn by the authors and significantly changed beyond recognition do not require permission.
