When an email address goes bad

July 25, 2012

Authors register with the RePEc Author Service using their email address, which serves as a user name. That email address is also used by the service to alert them about new potential works to add to their profile and to send them monthly statistics. Occasionally, some of these emails bounce back to the service: the mailbox is full, or the address has become obsolete. What happens now?

First, EconPapers and IDEAS add a mention to the author profile page encouraging users to supply a new email address to the RePEc Author Service. IDEAS also publishes the complete list of lost authors.

Second, lost authors are considered without affiliation for ranking purposes. Indeed, a major reason why an email address goes bad is that the author has moved, in which case the affiliation is likely obsolete. Another reason may be that the author has died, in which case having an affiliation make no sense.

Third, once the email address has remained bad for a second month, the administrator of the RePEc Author Service goes fishing for a better one. This involves Internet searches, asking co-authors and former colleagues. This is repeated later if necessary.

These efforts have allowed to keep the number of lost authors remarkably low: currently 273, or 0.8% of all registered authors. To this, add 152 authors who are known to be deceased. The records of the latter continue to be maintained by volunteers, as research may still be added posthumously, or new archives may still join with works written by these scholars.

We appreciate any help in tracing lost authors, notifications about deceased authors and support in maintaining their profiles. Simply email the administrator of the RePEc Author Service.

RePEc in June 2012

July 3, 2012

First off: RePEc is now 15 years old. It was launched at a meeting in Guildford (UK) where Thomas Krichel exposed his idea to a group of people who were already doing some indexing of working papers. Soon thereafter, they started providing the relevant bibliographic metadata in the relevant format and RePEc services could use them. Thomas Krichel had previously been running various initiatives to improve the dissemination of working papers, all the way back to 1991.

Speaking of volunteer personnel, Kyle Fluegge stepped down as NEP editor. His successor is Laura Stefanescu, who is now in charge of creating the weekly list of new working papers submitted to NEP editors, who can then select those relevant to their field.

During June 2012, we counted 520,118 file downloads and 2,010,606 abstract views. We also welcomed the following new participating archives: : HERMIN, Società editrice il Mulino, Catalactica NGO, Bangor University, Missouri Valley Economic Association, Université Bordeaux 4, University of New South Wales (III), Japan Ministry of Finance, Rockwool Foundation, University of South Bohemia, Babes-Bolyai University.

Finally, the following thresholds were reached during the past month:
400000 working papers available online
100000 articles with references
15000 book chapters available online
1500 indexed journals
500 blogs linked on EconAcademics.org with discussions about RePEc material

RePEc in May 2012

June 4, 2012

We counted in the past month 620,959 file downloads and 2,338,668 abstract views. RePEc has also grown to include now over 1.2 million items. This growth comes in part from the following newly participating archives: Lucius & Lucius Verlag, BI Norwegian Business School, Superintendencia de Pensiones de Chile, Rivista Bancaria, Harvard University (II), University of Tokyo (II), Universidade Técnica de Lisboa, Université de Liège, Flinders University, Economics for Energy, Central European University, Hellenic Association of Regional Scientists, Southern Regional Science Association.

And last month, we passed the following thresholds:
200000000 cumulative abstract views on IDEAS
8000000 references extracted
1200000 research items listed on RePEc
400000 items with citations
100000 articles with JEL codes
5000 identified links from blog posts to research items on RePEc
2000 links from Wikipedia to research items on RePEc

RePEc in April 2012

May 3, 2012

The innovation of the month is the complete overhaul of EconAcademics.org, 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:
250000000 cumulative abstract views
25000000 cumulative article downloads
7500000 references extracted from documents
3000000 references matched with documents in RePEc
750000 item abstracts
250000 JEL coded items
200000 JEL coded papers
70000 NEP subscriptions
12500 listed institutions
10000 book abstracts
1400 participating archives

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).
