Unlocking Scopus API for Full Author Access: A Guide to Complete Data Retrieval

When conducting a bibliometric analysis, having comprehensive access to author information is crucial. If you've ever used the rscopus package to perform searches through the Scopus API, you may have encountered a common dilemma: while the initial search results might provide you with the necessary titles and abstract information, they only return data for the first author of each article. This can be incredibly limiting, especially for in-depth research that requires full author listings. But fear not! This guide will guide you through the steps needed to retrieve a complete list of authors using the Scopus API.

The Problem: Limited Author Information

As a researcher utilizing the rscopus package, you may have tried using the scopus_search() function to retrieve data from Scopus. After running your query, you might have noticed that it only returns details for the first author of each published article, which isn't sufficient for a thorough analysis. This limitation typically indicates an issue with API access permissions rather than a programming error or flaw in your code.

Example Query

Here’s the query used for testing:

The Solution: Ensuring Correct API Access

After investigating the issue, the breakthrough moment came when I realized that my access problem was linked to the VPN I was using. The university’s VPN assigned an IP address that was outside the range allowed by my institution’s Scopus license, thereby restricting my access to only basic author information.

Steps to Resolve the Issue

Follow these steps to retrieve complete author data:

Check Your VPN Settings: Ensure that you are connecting through a VPN that is within the range of your institution’s Scopus license. You might need to consult your IT department for assistance in this matter.

Obtain an Institution Key: I reached out to Elsevier's support to acquire an institution key, granting me the necessary permission to access COMPLETE results from the API.

Modify Your Search Query: Once you have secured the institution key, update your search code to include this token in the headers. Here’s how the modified code should look:

Understanding the Code Changes

View Parameter: Changing the view parameter to COMPLETE allows the API to return full details, including all authors and their affiliations.

Headers: Implementing the institution token in the headers is crucial to authenticate your request and gain the necessary access.

Conclusion

By investigating the limitations of your rscopus implementation and adjusting your access permissions, you will be able to unlock a wealth of bibliometric data, including full author listings. These adjustments not only enhance the quality of your research but also ensure that you have comprehensive information at your fingertips. If you find yourself in a similar predicament, remember the importance of verifying your VPN connections and obtaining the right credentials for your API access. Happy researching!
