Reproducing Published Material from Other Publishers

Authors are urged to obtain permission to reproduce any published material (figures, schemes, tables, or any text extract) not falling into the public domain or for which they do not hold the copyright. Authors should request permission from the copyright holder, typically the Publisher (refer to the imprint of 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 copyright.

Permission is not required for:

  • Reconstruction of your own table with data already published elsewhere. In such cases, proper citation of the data source as "Data from..." or "Adapted from..." is necessary.
  • Reasonably short quotes are considered fair use and 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.

Obtaining Permission

To avoid unnecessary delays in the publication process, authors should initiate the permission process as early as possible. If there is any doubt about copyright, authors should seek permission. NOIS Journal cannot publish material from other publications without proper authorization. The copyright holder may provide specific instructions for acknowledgment; otherwise, authors should follow the style: "Reproduced with permission from [author], [book/journal title]; published by [publisher], [year]."
