Free check, for a list

Check a list of authors or ISBNs

Upload a CSV or Excel file with author names or ISBNs. You get the free check for every row: whether it appears in the pirate-library catalogs and how many candidate copyright registrations match. Then choose the rows you want full reports for.

1. Choose your file

A CSV or Excel (.xlsx) file with one name or ISBN per row, up to 500 rows a day. A header row is fine. Your file stays in your browser; only the names or ISBNs in the column you pick are sent for checking.

4. Get full reports

Tick the rows you want reports for. For one name, the Report link opens the usual check and checkout. For several, send us the list and we will reply with a quote that includes a volume discount.

What the free check shows

For a name: how many catalog records list it, in which sources, how many of them carry a candidate U.S. copyright registration, and how many meet the registration-date screen for at least one documented download. For an ISBN: whether LibGen lists it, whether it appears among the ISBNs found in the Books3 files, and how many candidate registrations match. A match means a record appears in that source; it does not establish that anyone copied the book. See what a match shows and the methodology.
