Importing from Reference Manager
I have a Reference Manager database with 33,000 entries that dates to the early 1990's that is indexed by "Reference ID #" (RID) with many very-useful-to-me printed out pdf's filed by RID#. These files take up more than a couple of file cabinet drawers. Is there any way preserve access to this filing system with Zotero? Can this RID# be imported into a Zotero database and retained as the primary method of indexing, searching, and filed-pdf access?
If it is, it can likely be imported and stored somehow, though would almost certainly require customization to do so.
I'm not sure what exactly means -- Zotero has its own item keys, so I guess the answer would be no, but really depends on what, specifically, you need in terms of functionality..
