Hello, same question as in this old thread https://forums.zotero.org/discussion/6821/book-price ? I assume the "rights" field is in French the "autorisations" field ; but is there a field - and a way - to export files in order to sum up the prices ? If not, does someone knows of a freeware that would be able to do it, and that would be compatible with Zotero ?

(just to explain, I'm transitionning from working in research fields to opening up a library - as the project is on-going, I am not yet using professionnal library softwares, which are often very expensive...)
