Text and Data Mining

Citation metadata, including citation counts can be accessed through the Scopus/ScienceDirect API

EBSCO databases allow researchers to download up to 25,000 citations at a time. This can only be done from a results screen and does not allow you to select individual articles. Note that this is only the citation information and not the full text of the articles. It does include abstracts, in most cases.
​Follow these steps

1. Conduct your search
2. Click on Share
   
3. Select Email a link to download exported results and select your desired format
   
4. You'll receive an email when the file is ready. This usually takes just a few minutes.

The entire PubMed bibliographic database can be downloaded for local use or accessed via API. This is citation and abstract information only, not the text of the cited articles.
