the author of this app says:
If you use EndNote bibliographic software and have a Palm, you've probably wished there was a way to either bring specific citations with you to the library on your Palm, or enter citations on your Palm to later upload to Endnote.
With PocketCites, you can do exactly this.
PocketCites for Windows converts exported EndNote records to JFile databases (and then back to files), which can then be imported into EndNote.
EndNote versions 3 and later are supported.
