Price and sum of price
I use Zotero to manage my scholar references and also I manage the acquisition book requests of my university department colleagues. Formerly I used Zotero and stuff like Booxter and Book Collector, but now I am using Zotero only, for the convenience of managing my entire references in a single and integrated place. I am using "rights" to store the price of the books but having a chance to sum the prices of the selected books would be my feature now. Anyway thank you all for all the work with Zotero.
Also, please don't double-post https://forums.zotero.org/discussion/6821/book-price/#Item_4
as bdarcus says in the other thread, the recommendation here would be to export to a spreadsheet. This may be useful:
