How do I get a link scheme so that I have article-level linking?

If the Link Scheme field is filled in, but article-level linking not working:

Sometimes a link scheme is set for a collection but an access link won't display. This can be because the citation doesn't have enough information. Each link scheme is unique in what it requires. A lot of link schemes require information such as a volume, issue and start page but others only need a volume or an article title. Contact OCLC Support with a link to the article in WorldCat Discovery.

If the Link Scheme field is empty:

1. See this article to determine if an existing link scheme will work: How do I identify what the link scheme is for a collection in order to add it?
2. Test the existing link schemes for the provider.
   • If none of the existing link schemes work, see: Request OCLC create a link scheme for your collection

We check several things to see if we can provide an article-level link, including:

1. Does the provider offer an OpenURL which we can build a link out of  
2. Does the provider offer a standard URL to articles which we can build a link using citation data such as volume, issue, start page 
3. Does the provider have DOI linking 
4. Can we use the provider’s search feature to offer a link to their article 
5. Does the provider have a table of contents page we can offer a link to that is broken down by year, volume, and/or issue

Link schemes and ebooks:

Not all ebooks can be linked-to in the chapter. Most ebook providers only allow for a link to the book’s title level. To request a linkscheme for an ebook, contact OCLC Support and provide the following:

• Your institution's OCLC symbol
• The ISBN, date
• start page/artnum (artnum = article number)
• A username and password that will allow OCLC to proxy through to the provider platform
