For what it's worth, Pinboard also has an API that you can use to manage your data, including making backups.
I use it for exactly that, especially since he's quite upfront (and funny) about how hooped everyone could be if he's ever hit by a bus.
First thought for easy digitization of hand written notes is an iPad with pencil by your workstation. A BKM for integrating that into your Zotero workflow isn’t obvious though.
Does BKM stand for bookmark manager or something else? I tried searching for "BKM" but didn't come up with many (relevant looking) hits.
As Luhmann did, I'm trying to more frequently write summaries of articles—both actual academic articles and things like blog posts, news articles, even recipes. I prefer to handwrite these notes.
For web links, I was thinking of using pinboard's caching feature which assigns a url like https://pinboard.in/cached/01234567890a/ and recording down the 48-bit identifier.
Alas, what happens when my online service of choice fails? So, maybe the Zotero citation key?
I'm wondering what others' experiences are with hybrid written/digital research workflows, and cross-referencing. Anyone have a "personal DOI" that works really well?
