| | | If you belong to a university or research institute, use the library’s discovery portal or ask a librarian. Many libraries can locate a paper from a cryptic internal reference. | | 4. Look for a pre‑print or open‑access version | Authors sometimes post PDFs on personal webpages, institutional repositories, or sites like ResearchGate, Academia.edu, or Zenodo. A simple web search for the title (once you have it) plus “PDF” often finds these. | | 5. Request via interlibrary loan (ILL) | If the paper is behind a paywall and you cannot obtain it directly, your library can usually request a copy from another library. | | 6. Contact the authors | Authors are usually happy to share a copy of their own work for personal use. Look up the corresponding author’s email on the abstract page or on their institutional profile. |
