RePEc in April 2012

May 3, 2012

The innovation of the month is the complete overhaul of, the blog aggregator for economics research. It now monitors a much longer list of blogs and selects the blog posts that discuss research. Also, IDEAS now links back from the abstract and author pages to the posts.

We counted 634,507 file downloads and 2,319,912 abstract views during last month and welcomed the following new participating RePEc archives: Kasetsart University, Review of Agrarian Studies, Brigham Young University, Karl-Franzens-Universität Graz, Bahcesehir University, JICA Research Institute, La Trobe University (II), Western Risk and Insurance Association, IGI Global, Barcelona Graduate School of Economics, Universitatea Andrei Saguna, Scientific Society of Management from Romania, Duke University (II), and Università di Trieste.

Finally, we passed the following thresholds:
3000000 matched citations
2500000 cumulative downloads through NEP
2000000 cumulative abstract views for book chapters
700000 listed articles

How does RePEc get its data?

April 24, 2012

The RePEc team regularly gets requests to from authors to add this or that item to the database, or enquiries from editors why RePEc is discriminating against their journal by not listing it. It is therefore useful to discuss again how RePEc gathers all its bibliographic data, and thus what various users can do to enhance the listings.

RePEc does not have any data entry staff, one because RePEc has a budget of zero, two because the data entry is done by the respective publishers. The same rules apply to all, whether it is a large commercial publisher with many journals or a small research center with a working paper series: they have to open a local metadata archive with bibliographic information formatted in a way that RePEc services can automatically gather and analyze on a regular basis (usually every night). So far, over 1400 archives have followed the detailed instructions necessary for participation. Authors with institutions that fail to participate in RePEc can still get their work listed, by uploading it with MPRA. They need copyright clearance for this, which is granted by most publishers, according to the list compiled by SHERPA/RoMEO.

Author profiles are also maintained by the authors themselves, by registering at the RePEc Author Service. The citation analysis (CitEc project) also depends on the collaboration of publishers, either by allowing the free download of the full texts or by providing the metadata about references separately.

The extremely decentralized nature of RePEc is what allows to reduce central costs to almost nothing and thus keep RePEc free for all: publishers, authors, and readers. The collected data can then be offered by the various RePEc services, and those bear the (small) cost of massaging the RePEc data to make it useful for everyone.

RePEc in March 2012

April 5, 2012

The big news this month is the launch of a new RePEc service, CollEc, which analyzes co-authorship networks within RePEc. Data from CollEc is now also integrated in author rankings. Furthermore, IDEAS now links back to any Wikipedia article mentioning a RePEc page (details). And the RePEc home page was redesigned. Watch this space, more initiatives are on the way.

We counted 684,729 file downloads and 2,385,381 abstract views through reporting RePEc services. We also welcomed the following new participating RePEc archives: Cornell University (II), Central European Labour Studies Institute (CELSI), ISTIEE, Universidade de Vigo, Kammer für Arbeiter und Angestellte für Wien, and Okan Üniversitesi.

Finally, we passed the following thresholds:
150000000 cumulative working paper abstract views
300000 JEL coded items
40000 registered people

RePEc in February 2012

March 2, 2012

The big news this month are the release of an upgrade of the RePEc Author Service and the new layouts of IDEAS and EDIRC. We hope this will improve the satisfaction of our many users, who were responsible for 642,216 file downloads and 2,276,448 abstract views. This leads us to the next big news: since the start, a quarter billion abstract views have been counted by the statistics-reporting RePEc services.

We also want to welcome the following new participating archives: International School for Social and Business Studies (Slovenia), University of Warwick (III), Università di Roma La Sapienza (IX), University of Toronto (III), Copernicus University in Torun (Poland), Columbia University (II), Banco Central de la Republica Argentina, Auckland University of Technology, Université d’Aix-Marseille, and St. Olaf College.

Finally, we have reached the following thresholds, and the list is long:

25000000 cumulative article downloads
7500000 references extracted from documents
3000000 references matched with documents in RePEc
750000 item abstracts

RePEc in January 2012

February 3, 2012

We made much progress in RePEc, at least contentwise. There are now over 5000 series covered in RePEc, among them 3300 working paper series and 1400 journals. We welcome a series of new participating archives: University of Otago, Rosenberg e Sellier Editori, Universität Mannheim, Hacettepe University, Hogeschool-Universiteit Brussel, Centre for European Policy Studies, Versita, and Universidade Técnica de Lisboa. We counted 599,360 file downloads and 2,026,510 abstract views during the month. For articles, this pushed us over 25 million downloads. There is a new NEP report on Transport Economics. And we reached the following benchmarks:

25000000 cumulative article downloads
700000 items with abstracts
700000 items listed in author profiles
300000 items with references
15000 listed book chapters
5000 listed series

RePEc in December 2011 and a look back at 2011

January 3, 2012

And another year has passed, and it is our duty to look back at what happened. But first the monthly update. In December we counted 583,840 file downloads and 2,025,144 abstract views, which is on the low side, with a strong seasonal component. Yet, RePEc continues to expand, with new participating archives from the following institutions: Universität Zürich (IV), Fondazione Aristide Merloni, University of Chicago (II), E3 Journals, INRA (VII), State Audit Office of Hungary, Université Dauphine (II), Instituto de Políticas y Bienes Públicos (IPP), Asian Economic and Social Society. In terms of thresholds passed, we can report:

200000 cited articles
50000 monthly downloads through NEP (in November)
2500 software components listed

Regarding the year: RePEc content continues to grow at unexpected rates: 157,000 research items were added, 152,000 of which are available online, covering in part 166 new journals and 303 new working paper series. 126 new archives joined RePEc and 4100 new authors registered. All these numbers cannot hide, though, some stagnation in traffic (8,235,237 downloads and 28,089,999 abstract views), with only NEP, our email notification service, registering significant growth. But we are hopeful that several product innovations in the coming months will drive traffic back up. Follow this blog for the announcements!

RePEc in November 2011

December 4, 2011

RePEc continues to grow in ways we would never imagined only a few years back. For example, this month, we surpassed the amazing number of a million works listed in RePEc and available in full text. Or, 460 new authors signed up with the RePEc Author Service in the past month. And we continue to have a steady stream of newly participating archives. In November, these were: Hungarian University of Transylvania, Indian Econometric Society, University of Connecticut (II), Maastricht School of Management, European Historical Economics Society, Cato Institute, Universidad del Pacífico, Harvard University (II).

RePEc in October 2011

November 4, 2011

The highlight of the month is the RePEc Author Service, which has recently welcomes its 30,000th registered author, and continue to get more at a never decreasing rate. Also, the service recently moved to the Economic Research Division of the Federal Reserve Bank of St. Louis, which provides hardware, hosting and maintenance.

We also welcome new RePEc archives: University of Hyogo, University of Chicago, African Studies Center, Universitat Jaume I, Chung-Ang University, New York State Economics Association, International Microsimulation Association, Teagasc, University of Sydney (II), Hiroshima University, Universidade de São Paulo, Weissberg SRL.

Finally, these are the thresholds we reached:
200000 papers with references
30000 registered authors
5000 online books

RePEc in September 2011

October 4, 2011

We welcome everyone back from the Summer slumber, as traffic is on the increase again at RePEc: 607,566 file downloads and 2,172,027 abstract views. While these numbers are lower than for September in recent years, this is due to the gradual tightening of what is considered a unique and valid abstract view or download by a human as we keep refining these criteria to prevent fraud and abuse.

Over the past month, we also welcomed a series of new participating archives: International University of Japan, Universidade Federal da Paraíba, Società Italiana di Economia dei Trasporti e della Logistica, Fundación ARU, Pro Global Science Association, Universitatea de Vest (Timisoara), Bucharest Academy of Economics Studies (III), Universidade de São Paulo.

Finally, RePEc reached a number of thresholds:

240,000,000 abstract views
1,111,111 indexed items
666,666 items listed in author profiles
350,000 cited items
333,333 articles with abstracts
200 book series

September 6, 2011

It is time to get out of the Summer slumber. We experienced some relatively light traffic over the past month, with 532,762 file downloads and 1,835,609 abstract views. Also, only six new archives joined RePEc: Latin American and Caribbean Environmental Economics Program, UNICEF, Saphira Publishing House, Association for Cultural Economics International, World Demographic and Ageing Forum, Universität Duisburg-Essen (II). But despite this light activity, we got some interesting thresholds passed during last month:

350000 online working papers
150000 cited working papers
33333 NEP reports created
30000 unique email addresses subscribing to NEP reports.
75 countries with RePEc archives
