OpenLibrary Search

This tool uses Perplexity AI Sonar to perform comprehensive web searches with synthesized, researched answers. Unlike simple search engines, Perplexity provides cited sources and contextual understanding. Best for research questions, current events, fact-checking, and queries requiring authoritative sources. Responses include citations and contextual analysis.

This tool searches OpenAlex, a fully open catalog of 240M+ scholarly works, authors, institutions, and topics. Returns comprehensive academic metadata including citations, open access status, author affiliations, publication venues, and subject classifications. Best for finding research papers, tracking citations, discovering authors and institutions, and analyzing academic trends. Supports advanced filtering by publication year, citation count, open access status, and more.

This tool delegates research and search tasks to a specialized subagent with access to multiple search tools (OpenAlex, OpenLibrary, Web Search, Perplexity). Useful for complex research queries that benefit from using multiple search sources or when you want a specialized research assistant to handle the search comprehensively. The subagent can orchestrate multiple tool calls and synthesize findings across academic, web, and book searches.
