Zotero is a free and easy-to-use research tool that helps you collect, organize, and analyze research and lets you share it in a variety of ways. Zotero includes the best parts of older reference manager software — the ability to store author, title, and publication fields and to export that information as formatted references — and the best aspects of modern software and web applications, such as the ability to organize, tag, and search in advanced ways. Zotero interacts seamlessly with online resources: when it senses you are viewing a book, article, or other object on the web, it can automatically extract and save complete bibliographic references. Zotero effortlessly transmits information to and from other web services and applications, and it runs both as a web service and offline on your personal devices. From https://www.zotero.org/about/
Zotero supports PDF fulltext indexing. Currently this function relies on modified versions of
pdfinfo and as such require their installation via the Search panel from within Zotero Preferences. See https://forums.zotero.org/discussion/31731/zotero-debian-gnulinux-and-pdftotextpdfinfo/ for further information.
Alternatively you can install zotero data folder.AUR from AUR and create appropriate symlinks in
$ cd ~/.mozilla/firefox/Profiles/<randomprofilename>/zotero $ ln -s /usr/bin/pdfinfo pdfinfo-Linux-x86_64 # File name for your arch $ ln -s /usr/bin/pdftotext pdftotext-Linux-x86_64
