RePEc has been disseminating almost from its start in 1997 new working papers through NEP (New Economics Papers). When RSS feeds became popular, that means of dissemination was added. And now that scholars have adopted Twitter, NEP is there, too.
Each of the about 90 field-specific reports is now tweeting. The papers are hand-picked by academic volunteer editors among all new working papers that are available online. As the email reports may contain several dozen papers in each weekly mailing, the tweets are throttled to no more than one an hour for each report. To subscribe, log into Twitter, go to the NEP home page, click on the report(s) relevant to you, then click on the Twitter link and finally the follow button.
As all RePEc projects, this service is of course free.
