scanning book barcodes and import into zotero

Silvy

I plan to create a zotero collection by scanning book barcodes and importing them into Zotero ; I would like to know from where the metadata are imported ? one source ? several sources ? which ones ?
can you explain the process to me ? (= how does it work ?)

it depends on the app you're using to do that, but from what I know they all use open WorldCat.
