The model proposed in this post is similar to that of RePEc (Research Papers in Economics)[1] and arXiv[2]. I've only used arXiv via their search but the NEP service[3] within RePEc offers curated mailing lists of recent economics working papers by specialty area. > NEP is an announcement service which filters information on new additions to RePEc into edited reports. The goal is to provide subscribers with up-to-date information about the research literature. Our success in achieving this goal has been substantial. Today, there are 80541 subscriptions from 34926 unique addresses distributed throughout the world. The reports are generated by subject-specific editors. They are available by email and RSS feeds.
