We show that the e\u2010prints have not undermined the usage of journal papers from the four core journals in astrophysics. As soon as the journal article is published, the astronomical community prefers to read it and the use of e\u2010prints through the NASA Astrophysics Data System drops to zero. This suggests that most astronomers have access to institutional subscriptions and that they choose to read the journal article. In other words, the e\u2010prints have not undermined journal use in this community and thus currently do not pose a financial threat to publishers. Furthermore, we show that the half\u2010life (the point at which the use of an article drops to half the use of a newly published article) for an e\u2010print is shorter than for a journal paper.<\/jats:p>","DOI":"10.1087\/095315107779490661","type":"journal-article","created":{"date-parts":[[2007,1,14]],"date-time":"2007-01-14T22:58:55Z","timestamp":1168815535000},"page":"16-22","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["E\u2010prints and journal articles in astronomy: a productive co\u2010existence"],"prefix":"10.1002","volume":"20","author":[{"given":"Edwin A.","family":"HENNEKEN","sequence":"first","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Michael J.","family":"KURTZ","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Guenther","family":"EICHHORN","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Alberto","family":"ACCOMAZZI","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Carolyn S.","family":"GRANT","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Donna","family":"THOMPSON","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Elizabeth","family":"BOHLEN","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Stephen S.","family":"MURRAY","sequence":"additional","affiliation":[{"name":"Harvard\u2010Smithsonian Center for Astrophysics  60 Garden Street Cambridge MA 02138 USA"}]},{"given":"Paul","family":"GINSPARG","sequence":"additional","affiliation":[{"name":"Cornell Information Science  Ithaca NY 14850 USA"}]},{"given":"Simeon","family":"WARNER","sequence":"additional","affiliation":[{"name":"Cornell Information Science  Ithaca NY 14850 USA"}]}],"member":"311","published-online":{"date-parts":[[2007,1]]},"container-title":["Learned Publishing"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1087%2F095315107779490661","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1087\/095315107779490661","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,23]],"date-time":"2023-11-23T03:13:09Z","timestamp":1700709189000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1087\/095315107779490661"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2007,1]]}},"alternative-id":["10.1087\/095315107779490661"],"URL":"https:\/\/doi.org\/10.1087\/095315107779490661","archive":["Portico"],"relation":{},"ISSN":["0953-1513","1741-4857"],"issn-type":[{"value":"0953-1513","type":"print"},{"value":"1741-4857","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,1]]},"assertion":[{"value":"2007-01-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
