Research Papers Management With Zotero and Yandex.Disk

Zotero is an open source plugin for Firefox for managing research papers collections. You can use online zotero storage (pretty small) or use third-party sync application. I use Yandex Disk for this purpose: 10 Gb it quite enough for a moderate research library. zotero can automatically fetch article metadata (author, year, etc) from the web (like Mendeley and similar software do).
