VERDICT

Should I use WorldCat.org?

WorldCat.org is a global catalog of library materials. You can search for books, music, video, articles and much more at libraries near you. - worldcat.org

Worth it. Use it if you need to find which libraries worldwide hold a book, recording, or article — it is free and unmatched in scope. Skip it if you want full-text access, modern search UX, or guaranteed access from every region.
