About this extension
ScholarKey is an open-source extension that loads database access links beside DOI URLs. It is pre-loaded with SciDB and Sci-Hub, and it's easy to add other databases such as your university library search.

Usage

Browsing: Visit any webpage with DOI links (e.g., academic journals, Google Scholar). The extension automatically adds emoji links next to each DOI.

Configuration: Click the extension icon in the toolbar to open settings.

Adding Custom Sources:
Click "+ Add Custom Source"
Enter an emoji (e.g., 🔬, 📚, 🎓)
Enter a source name

Managing Sources:
Check/uncheck to enable/disable
Use ▲▼ buttons to reorder
Click ✕ to delete custom sources

URL Template Format

Use EXAMPLE_DOI as the placeholder in your URL template. The extension will replace it with the actual DOI.

Semantic Scholar: https://www.semanticscholar.org/search?q=EXAMPLE_DOI
