This click-through agreement (the "Agreement") contains the terms and conditions applicable to use of the CrossRef system via the CrossRef OpenURL Service. Please read it carefully.

TERMS & CONDITIONS FOR NON-COMMERCIAL USE OF THE CROSSREF OPENURL SERVICE AND MATERIALS

1. Manner of Use.

 a. The Account Holder may retrieve DOIs and metadata via the CrossRef OpenURL Service. The Account Holder may use retrieved DOIs and metadata to make persistent links to full-text works online, to make link resolvers function better and clean up its own indices, abstracts and record locators, the Account Holder may cache the DOIs and incorporate DOIs into their content and systems. The Account Holder may use the DOIs and metadata for scholarly, research, educational, personal or non-commercial purposes. If the Account Holder wishes to make commercial use of the DOIs and metadata and/or wishes to integrate the CrossRef OpenURL Service into a commercial product or service then Account Holder must become a CrossRef Affiliate as defined on the CrossRef website (http://www.crossref.org/).

 b. Any other use of metadata is prohibited. For example, the Account Holder may not, and may not permit others to, use metadata to create tables of contents, abstracts or indices. For avoidance of doubt, the Account Holder may not, and may not permit others to, redistribute, copy, print, archive, backup, reserve or loan any of the metadata (except incidentally where DOIs and metadata have been incorporated into the Account Holder's content and/or systems.)

 c. The Account Holder may not charge fees for access to the CrossRef system or retrieval of DOIs and metadata. Likewise, the Account Holder may not re-license or sell the DOIs and metadata or access to the service, including but not limited to bulk reproduction or distribution of the DOIs and metadata.

2. Access to Full-Text Works. Access to full-text or other copyrightable works described or identified by the DOIs and metadata ("targeted works") is pursuant to any agreement(s) between the Account Holder and the corresponding publisher(s), and not granted by CrossRef under this Agreement.

3. Term, Termination and Renewal. The initial term of this Agreement is twelve (12) months. Either party may terminate the Agreement for any reason upon thirty (30) days written notice to the other. This Agreement will automatically renew for subsequent twelve (12) month terms unless terminated. The email address designated by the Account Holder will be emailed any revisions to this Agreement and Account Holder may terminate the Agreement if revisions are not acceptable.

4. Permissive Use of CrossRef Trademarks. CrossRef grants the Account Holder the nonexclusive and revocable right to use the name and trademark "CrossRef" during the term of the Agreement in conjunction with activities described by the Agreement. The Account Holder’s use of the mark shall be subject to CrossRef's reasonable ongoing approval over its form, associated content and presentation. For avoidance of doubt, this license to use the mark does not extend to any of the Account Holder's customers, partners, affiliates or other entities, and may not be used constructively by the Account Holder in association therewith without the prior written consent of CrossRef.

5. Limitations and Disclaimers. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW, CROSSREF SHALL NOT BE LIABLE FOR ANY DAMAGES (DIRECT, INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, REVENUE, GOODWILL OR OTHER ECONOMIC ADVANTAGE, OR BUSINESS INTERRUPTION), EVEN IF THE LIBRARY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING OUT OF THE USE OF OR THE INABILITY TO USE THE CROSSREF SYSTEM. FURTHER, CROSSREF MAKES NO REPRESENTATION OR WARRANTY, AND EXPRESSLY DISCLAIMS ANY LIABILITY WITH RESPECT TO ANY DOIS, METADATA OR TARGETED MATERIALS, INCLUDING FOR INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS INCLUDING COPYRIGHT, TRADEMARK, PATENT OR TRADE SECRETS. FINALLY, THE DOIS AND METADATA AND ACCESS TO THE SYSTEM ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, AND CROSSREF DISCLAIMS ANY AND ALL OTHER WARRANTIES, CONDITIONS OR REPRESENTATIONS (EXPRESS, IMPLIED, ORAL OR WRITTEN), RELATING TO THE DOIS AND METADATA, THE CROSSREF SYSTEM, OR ANY PARTS THEREOF.

6. Waiver. The parties agree that no delay or omission by either party to exercise any right or power hereunder shall impair such right or power or be construed to be a waiver thereof.

7. Entire Agreement. This Agreement constitutes the entire agreement of the parties regarding its subject matter and supersedes any prior communications.
