The extension does the following:
I did create a black and white version of the Bookends icon, however the detail is too fine to show up at all in PopClip, so I've temporarily used a basic open book icon. If anyone has anything better, just send it along. I'd love to spruce it up.Add selected DOI, PMID, ISBN, or JSTOR stable URL to open library. If ⌘ is held, then search library for selected text and create new group with references returned.
Also, if anyone has any ideas for other features that might be included, I'd be happy to implement so long as the general population might find them of use--anything, then, that isn't too idiosyncratic. It's quite easy to add other functions that might be activated by holding down other keys when clicking the Bookends extension in PopClip.
Finally, to Jon, don't hesitate to let me know if you don't want your app distributed in this way. The plist checks for the bundle id and directs users to Sonny Software if not already installed, so it can (I hope) only help awareness of the app.
