Store the file with its canonical source, publication date, and a note about the pages that matter.

Keep the PDF details in a note

A file named report-final-2.pdf tells you little about its origin. Before renaming it, identify the document's own title, author or institution, publication date and version. Keep these in a separate note so a later filename change does not remove the citation.

Zotero note editor for recording context beside a source.
Example in Zotero. Keep title, author, version and source in a note that survives a filename change.Zotero

Build the PDF record

  1. Identify the original

    Use the document itself and its original landing page. Distinguish publication date from the date you downloaded it.

  2. Keep a usable file

    Open the downloaded original. If the PDF is a scan, check whether text can be selected or searched. OCR can help, but check names and numbers against the page image.

  3. Locate the useful evidence

    Record printed page numbers and PDF page positions when they differ. Add a brief reason for keeping the passage.

  4. Test a second route

    Retrieve the document through its project and through a remembered term. Open any exported or independent copy.

Zotero PDF reader with page thumbnails, highlights and source-linked notes.
Example in Zotero. The viewer shows position 2 of 8 while the cited passage belongs to printed page 868.Zotero

Record page numbers without ambiguity

With four unnumbered initial pages, printed page 12 appears at PDF position 16.
The viewer position and printed number can differ. This offset is only an example.Signoapp

Keep source, file and note connected

The Library of Congress personal digital archiving resources cover formats and descriptions. The Web Annotation Data Model gives a separate model for relating a note to its target. They help describe a file and link it to notes. You will still need to check your copies over time.
