I&#x27;m not sure there&#x27;s any one tool that fits my needs, and I&#x27;ve looked at a few, Zotero among them.<p>My understanding is that it&#x27;s more a _bibliographic management_ tool.<p>There&#x27;s also Calibre, which seems like it&#x27;s a close solution, though that too is problematic, particularly at scale.<p>Another problem is that my laptop (as opposed to tablet) isn&#x27;t particularly useful for reading formatted documents -- PDFs can&#x27;t really be viewed _either_ one-up or two-up, and FBReader, which I like on mobile, formats ePub and similar eBook formats poorly (too wide, insufficient paragraph separation, unfamiliar controls), which is frustrating as well.<p>The tablet&#x27;s much superior for _reading_ but even worse for _organising_ material.
