Excellent if you have access to a subscribing library – BrowZine Review

Browzine is a front-end to journals available online from subscribing (largely academic) libraries. It is great for current awareness--having added journals to your private library, you can open it, see which journals have newly published articles, click to the table of contents and then click to read the article. It can export PDFs to almost any target through the share menu and, even better, send both citation and PDF to many bibliography managers incliude Zotero and EndNote. If you are after a specific article, it is equally easy. (I have learned from conversation with my librarian that Browzine is not able to show all journals to which a library subscribes because of publisher restrictions, so be sure to check your library's catalog before assuming you don't have online access to a journal that doesn't appear in Browzine). They have a web-based product for the desktop which, if you library has so subscribed, shows your private library. Personally, I find this less compelling, as I have bookmarks set for the journals I need to frequently access, but others might find it helpful.
