Linking to full content
Latest revision: 28 May 2003
All documents contained in the electronic resource should be easily discovered and located from any license held by the CDL or UC campuses when in electronic form, or in print form from any of the UC campuses. 
Linking to articles: CDL’s preferred method is a computable, dynamic link to the publisher’s site that will take the user directly to the article.  We should be able to create this link using the metadata commonly found in an OpenURL, i.e., 
•	ISSN or ISBN
•	Volume
•	Issue
•	Page
•	Date
We can also use CrossRef to discover DOIs.  If the publisher is a member of CrossRef, the CDL needs to be able to use metadata found in an abstracting and indexing database citation to establish dynamic links to the article at the publisher’s site. The CDL is willing to work with publishers that are members of CrossRef and DOI community to establish the dynamic links using the metadata in the CrossRef record to discover the DOI of the article. The CDL needs to be able to send queries to CrossRef in real time and use existing redirection methods to resolve the query to the full text of the article. The CDL needs commitment from publishers that are CrossRef members that ALL of the full text that is available on their web sites has a corresponding metadata record in the CrossRef database. Vendors using CrossRef should deposit the information within 24 hours after the content is added to the publisher’s web site. 
If you cannot support the OpenURL standard:  CDL will need your algorithm for computing article level URLs.
Linking from references in an e-journal article:  Our preferred method for this type of link is the OpenURL.  This requires that the e-journal vendor site be OpenURL-enabled. If these protocols are not supported, please describe other mechanisms for linking to your electronic content.
Contact information:  Vendors, please provide the name, e-mail address and telephone number for your staff member(s) that will serve as technical contacts to the CDL technical staff for content linking issues.
