Keyword search across PhilPapers / PhilArchive (philosophy preprints and published papers indexed by the PhilPapers Foundation), powered by OpenAlex full-text search. Returns title, authors, year, a short abstract, the PhilArchive record id + URL, and an open-access PDF URL when one exists. Use the returned id with get_paper, research, or fetch_pdf. For a richer one-shot digest with full abstracts, use research instead.

One-shot literature scan: runs a keyword search across PhilPapers/PhilArchive and, for each hit, fetches the archive's canonical metadata (verbatim full abstract, subjects, language) via OAI-PMH — so you get a ready-to-read digest in a single call instead of search_papers + get_paper per result. Returns fewer results than search_papers by default because it does more work per item.

Fetch canonical metadata for one PhilArchive/PhilPapers record via OAI-PMH. Accepts a record id (e.g. 'BROTNO-9'), a philarchive.org/philpapers.org /rec/ URL, or an oai: identifier. Returns title, authors, date, subjects, language, full abstract, the landing-page URL, and whether an open-access PDF is available.

List recently added/updated PhilArchive records in a date window, via OAI-PMH (harvesting, not keyword search). Returns the first page of results (~up to limit). Dates are UTC YYYY-MM-DD; defaults to the last 7 days.

Download the open-access PDF of a PhilArchive record and save it locally, returning the file path so it can be read. Accepts a record id or URL. Fails clearly if the paper has no open-access PDF. To get the text directly instead of a file, use get_fulltext.

Download a PhilArchive record's open-access PDF and extract its full text, returned directly (no file needed). Accepts a record id or URL. Long papers are truncated to max_chars. Fails clearly if the paper has no open-access PDF.

Search Project Gutenberg for public-domain classics and out-of-copyright translations (Kant, Hegel, Nietzsche, Schopenhauer, Marx, Fichte, ...). Returns title, author, languages, a Gutenberg page link, and download URLs. Use the numeric id with get_gutenberg_text.

Fetch the plain-text body of a Project Gutenberg book by numeric id (from search_gutenberg). Truncated to max_chars.

Search the Internet Archive for scanned, out-of-print monographs, journals, and translations. Use the returned identifier with get_archive_text.

Fetch the OCR full text of an Internet Archive item by identifier (from search_internet_archive). Truncated to max_chars.

Search Wikisource for primary texts and translations (en, de, ko, ...). Use get_wikisource_text to read.

Fetch the plain text of a Wikisource page by title (from search_wikisource). Truncated to max_chars.

Search Open Library for books — strong for modern editions and translations as metadata, with read/borrow links wherever a scan exists.

Search the Directory of Open Access Books — peer-reviewed, fully open-access academic books, including many modern philosophy monographs readable in full.

Search SEP (the standard scholarly reference) by matching its full entry index. Read an entry with get_sep_entry.

Fetch the text of a SEP entry. Accepts a slug (e.g. 'hegel'), a /entries/.. path, or a full URL. Truncated to max_chars.

Fetch any URL and return its readable text — the catch-all for sources without a dedicated tool: Zeno.org and projekt-gutenberg.org (German originals), marxists.org (German Idealism to Frankfurt School translations), Standard Ebooks, a specific page, etc.
