Its clean interface and comprehensive citation tracking make it invaluable for understanding research trajectories and identifying influential papers.
Google Scholar
While broader than just software engineering, Google Scholar:
- Indexes scholarly literature across disciplines
- Provides citation counts for papers
- Offers email alerts for new publications on specific topics
The "Related articles" feature helps discover relevant research that might not appear in direct searches.
Microsoft Academic
Formerly Microsoft Academic Search, it provides:
- Detailed bibliographic information
- Visualization tools for research relationships
- Author profiles with productivity metrics
Its semantic search capabilities often discover connections between research areas that traditional keyword searches might miss.
SE-RuS (Software Engineering Research using Search)
A specialized search engine for software engineering literature that:
- Focuses specifically on software engineering papers
- Offers filtering by research methodology
- Provides context for search results with automatic summarization
Its domain-specific indexing reduces false positives in searches compared to general academic search engines.
arXiv Search
The search functionality within arXiv includes:
- Advanced search across all fields including software engineering
- Filtering by date, author, and subject classification
- RSS feeds for new submissions in specific areas
Especially valuable for finding the most recent preprints in rapidly evolving areas of software engineering.
Web of Science
A subscription-based database that provides:
- Citation indexes for tracking research impact
- Journal citation reports for publication decisions
- Analysis tools for research trends
Particularly useful for literature reviews and bibliometric analysis of software engineering research trends.
