Archivists & historians, what programs would you recommend for organizing scanned pdfs of documents?
@duderonomy Zotero works well, but so could a regular folder structure anywhere you keep your files. Whatever program you use, it's how you structure the folders or tags that matters.

@dambaras @duderonomy I second Zotero - you will need a way to save and later access metadata of your documents & filenames are a poor solution for that.
(I'm not saying it can't suit your purpose)

And using Zotero it's very easy to keep the same file in different collections...
There even is the possibility for automatically renaming of the file based on metadata :)

@lavaeolus @dambaras Thanks, this is all great information!
I see that Zotero also offers extra storage as well.

@duderonomy @dambaras

Yes, but you don't actually need the storage for you files - just for the database (of metadata).

You can link to files on your local machine; and even use relative linking.
I'm using a different cloud for synching my files (and point zotero to the right directory on each machine) und zotero-sync for the database.
300MB ist enough for a database containing thousands of entries

@lavaeolus @duderonomy Agreed. I think it's best not to store pdfs inside Zotero because the database puts them into folders and names/organizes those folders as it sees fit,not as you might find convenient. If you keep the pdfs in a "Zotero pdfs" folder on, say, iCloud, then you can readily search them even if you don't have Zotero open.
