One entry per unique PDF, linked to the parts that use it, with duplicates caught on the way in.
Six copies of the same datasheet named DS_final(2).pdf, each linked somewhere different, is how packages go stale. The Document Library keeps one entry per unique file and points every part at it.
Browse the library
Open Documents to see every PDF your parts share: file name, type, size, linked parts, and when it was added. Search by file name or category; behind the filter disclosure, narrow by type (Datasheets, Manuals, Other) or show only files Not linked to any part, which is your cleanup list.

Upload without duplicates
Drop PDFs on the upload zone and pick how they file: as datasheets, manuals, or other. Re-uploading a file you already have always lands on the existing entry; a second copy is never created.
A vendor datasheet downloaded a second time is trickier, because the file differs even when the document doesn't. When a new upload reads the same as one you have, a Possible duplicate notice appears showing what it matched, when that was added, and links to open both, since two sheets in a product line can read alike and differ only in a photo. One click keeps the existing file and drops the copy, or Keep both if they really are different documents.
The document page
Open any file to manage it in one place:
- Link parts by searching, or unlink a part that no longer belongs; unlinking removes only that part's highlights on the file.
- Set the category, and for datasheets, Always full sheet, which ships the complete document even in Relevant Pages Only packages.
- Analyze all parts reruns page analysis for every linked part at once. See Part documents for what highlights and analysis do.
A library document can back parts across many projects, so editing a shared file's category or Always Full Sheet asks first, with live counts of the parts and projects linked to it. A document used in one place edits without ceremony.
Straight to the right page
Results from searching inside documents and links in highlight reviews open a document at the matched page, not page one, so a 90-page manual stops being a scrolling exercise.
A document with no linked parts can be deleted from its page. Anything still linked has to be unlinked first, which is exactly the friction you want in a shared library.
