There's no replacement for EndNote when… There's no replacement for EndNote when you want to inventory useful articles, find them again, and then footnote your paper. I have trouble syncing across Macs and also the pdf annotater is a bit limited compared to earlier EndNote versions. EndNote also sometimes corrupts my pdf's so I need to keep duplicates in a separate file. All in all, though, I couldn't live without the app.

I upgraded from several EN versions… I upgraded from several EN versions back. It was a little awkward to get used to EN21, but now that I have, I can appreciate some new features such as its remarkable ability to grab online PDFs without going through the usual hassles. There are a couple of older features that I miss, though: I used to be able to see a quick preview of a new reference in my chosen output format on-screen, without having to write it to an output file. (Maybe I just haven't figured out how to do that yet.) Also, on the Edit page the top toolbar is missing the Greek symbol conversion that used to be there. Also, it would be really helpful to give us a couple of highlight colors like yellow and red in that toolbar!

Outdated Error prone serviceable tool The interface is old and clunky—-and the importing of citations from the online database are just riddled with errors. End note has a tough time with Chicago and online citations—-treats internet like it is 1997. Please please please have a real researcher show you whats wrong.

Improved but some features need to return Drag and drop of PDF files is a fantastic addition. Overall user interface is good, but would prefer to maintain the ability to open the reference details window as a separate pop-out window, one that is not confined to being along side the reference library window. Makes it tedious to edit text, and some functions (i.e., change case) are missing.

Endnote is one of the most useful… Endnote is one of the most useful research tools I've ever used. I've been a user for more than a decade and am now successfully managing nearly 50,000 references on a variety of subjects. I've even converted many of my old graduate-school 5x8 cards to EN references. Love having all my notes fully searchable.
