How to Convert an OCLC to an ISBN
- 1). Go to the WorldCat website. Find the search options on the front page.
- 2). Click the "Advanced search" link. You will be taken to the advanced search page.
- 3). Find the input boxes for entering search terms. There will be three boxes available. Next to each box will be a pull-down menu. Click on the top pull-down menu, which will read "Keyword," and select "Accession number" from the list of options.
- 4). Input your OCLC number into the text box next to the pull-down menu. Click the "Search" button. If your OCLC number is correct, you will be taken to your desired publication's record in WorldCat.
- 5). Scroll down to the "Details" section of the page.
- 6). Find the row marked "ISBN." The numbers in this row are the ISBNs for this publication. Most publications have more than one ISBN. Each one is separated by a space.
