Mendeley is one of the popular and easy reference managing software. It can be installed in Windows, Linux and Mac OS. Combination of Mendeley with Zotero, another reference managing add-on of Firefox, could be very effective to run. Although it is one of the best for Linux OS, but it still has some limitations like abbreviation of journal's name, writing first capital letter for each word of name of journal, etc. are still limiting factors (or at least I assume). I hope, these limitation will be addressed in final stable release of this latest version. Please visit here to download and don't forget to back up Mendeley library.
