This is a follow-up to my previous question regarding the inclusion of a figure in my grant proposal.
I followed the necessary steps and obtained permission, which was granted free of charge. I received an email with the subject line 'Thank you for your order with RightsLink / John Wiley and Sons.' However, I am unsure whether this confirms that I have obtained permission.
Assuming that I do have permission, what do I do with it? Should I include a statement in the figure caption indicating that permission was obtained (include the order number)?
I have observed instances in which figures from one study were reused in another study, but I have never encountered cases where permission for such reuse was explicitly discussed in their captions.
The linked post (suggested duplicates) is not an answer for how to indicate permission, although it provides an example in which permission is noted. In particular, it states that one way to indicate that permission is obtained is to say:
Reproduced with permission from [ref]
However, citing the paper for permission is not necessarily accurate when the permission does not belong to the published paper itself.
Also, is proof of permission (e.g., License Number) not needed? Do you only have to provide proof when someone asks for it?
