Reproducing Published Material from other Publishers

It is no question 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.

For reproducing any published material (figures, schemes, tables or any extract of a text) permission should be requested by the authors from the copyright holder.

Permission is required for:

1. The work that you have published by other Publishers and you did not retain copyright.
2. Significant extracts from others’ works.
3. Use of tables, graphs, charts, and artworks if they are unchanged or slightly modified.
4. Photographs for which you do not hold copyright.

Permission is not required for:

1. Reconstruction of your own table with data already published elsewhere. However, the source of the data should be cited  in the form of either "Data from..." or "Adapted from...".
2. Reasonably short quotes do not require permission.
3. Graphs, Charts, Schemes and Artworks that are entirely redrawn and considerably changed by the authors do not require permission.

Obtaining Permission

To avoid unwarranted delays in the publication process, author(s) should start acquiring permissions as soon as possible. TJES cannot publish material from other publications without permission.
