A compendium of RePEc services

March 12, 2013

Since its formal founding 16 years ago, RePEc has grown into a large collection of various services. Users are aware of some, but not all of them. This is an attempt to collect all services that use RePEc data. RePEc is in fact just a way of organizing and collection bibliographic data in economics. Publishers index their works and put it in the public domain through RePEc. Service then use this data in various ways, in part by enhancing it. All linked services are completely free to users and managed by volunteers.

Browsing and searching the database

These are the most basic functions you would want to do with a bibliographic database. Several services provide this. The most popular are IDEAS and EconPapers. Others include Economists Online and Socionet. What distinguishes these services is that they report usage statistics (see below). Yet others that use RePEc include: EconLit, EconStor, Google Scholar, Inomics, Microsoft Academic Search, OAISter/WORLDCAT, Scirus and Sciverse. Shop around and use the one that is the most to your liking!

Curated material

While most the services above provide the complete RePEc bibliographic data, it is the user who has to sift through the material to find what she needs. A few services act as facilitators by helping users with the help of editors who sort and curate the material. NEP disseminates through email and RSS feeds the latest working papers across over 90 fields. The new RePEc Biblio determines the 10-20 most relevant papers in a growing number of fields and sub-fields. EconAcademics.org identifies economic research currently being discussed in blogs.

Specifically for authors

Some services are especially geared towards authors. The RePEc Author Service allows them to create a portfolio of all the works listed in RePEc. Other services then can link from the works to the profiles, and authors can get statistics and new citation notifications. CollEc analyses co-authorship networks and allows, for example, to find how many steps removed from each other any two authors are. The RePEc Genealogy allows to see who graduated where and when and who was the advisor. Finally, the RePEc Plagiarism Committee handles potential plagiarism cases and votes on them, in particular whether to name and shame offending authors.

Statistics

Several RePEc services report traffic on their website, which allows to compute a host of statistics, which are displayed at LogEc. Those, along with citation numbers, allow to compute a large number of rankings of authors, institutions, and papers, including impact factors for serials.

And more

As already mentioned, there is a citation analysis project, CitEc, which uses complex algorithms to extracts references from pdf files and match them with RePEc content.

MyIDEAS allows a user to track other authors, JEL codes, journals or working papers series, as well as build a personal bibliography while browsing on IDEAS. The Socionet Personal Zone also provides some of these functionalities.

EDIRC is a directory of economics institutions with plenty of links to affiliated authors and alumni, as well as compilations of their publications.

Finally, for those authors who do not have the benefit of their local institution participating in RePEc with its publications (see instructions), the Munich Personal RePEc Archive (MPRA) allows them to upload their papers to be included in RePEc.


The RePEc Biblio

February 25, 2013

We are proud to announce the launch of the latest RePEc initiative, the RePEc Biblio. This is a hand-selected collection of the most relevant articles and papers on a wide variety of economics topics. RePEc Biblio is organized as a tree, narrowing the topics as you follow its branches.

The RePEc Biblio lives from the contributions of volunteer editors. Consider helping out if you have taught a class on a topic and have already put together a literature list. Feel also free to contribute your vision of the best papers from your area of research. Volunteer editors are welcome to sign up to populate the tree, either by contacting the manager or the relevant topic editor who can open a sub-topic or sub-sub-topic. We are looking for editors in both the broadest and narrowest fields. And to encourage good editing, readers can rate the topic entries.

Note that IDEAS links from papers, articles, editor profiles, and JEL codes to the relevant RePEc Biblio topics. Authors also find mention of their papers in RePEc Biblio on their IDEAS citation pages.


News about EDIRC, the index of economics institutions

November 21, 2012

EDIRC is an index of economics departments, institutes and research centers created in 1995 that has been feeding RePEc with data about such institutions. But beyond just a listing of institutions, it has evolved into an information source of its own right. Currently, it has the following additional features:


  • Links to journals or working paper series published by the respective institutions and indexed in RePEc.
  • Listings of all people affiliated with the respective institutions and registered with the RePEc Author Service.
  • For these people, a link to a compilation of all their publications.
  • A recent add-on is a listing of all alumni (final degree) as found on the RePEc Genealogy.
  • For the alumni as well, a link to a compilation of their publications.

With close to 13,000 listed institutions, EDIRC has grown a lot since its start. After all those years, the database will now go through some gradual changes, among which are:


  • New categories: the current ones were designed when there were only a few hundred listed institutions.
  • About 12% of the links are known to be invalid. They are currently being systematically checked for better addresses, but this will take several months.
  • Institutions that are known to be defunct and that have no links to people or publications will be removed.
  • When possible, chairs and similar “micro-institutions” will be consolidated. They change too frequently and have become a maintenance burden with no significant benefit. This pertains particularly to Germanic universities.
  • An effort is currently being made to add translations of institution names to English wherever possible. Indeed, it appears that even natives users search for the English name.
  • Speaking of search, the search engine will be improved to make searches more intuitive and efficient than is currently the case.

Of course, any help is always appreciated. In particular, if you notice a bad link, a valid one is always appreciated. And you will be credited along with all the other contributors.


Introducing the RePEc Genealogy

September 28, 2012

A new RePEc service is born, the RePEc Genealogy, which collects and displays the academic family tree for economics. This is a crowd-sourced initiative, which means that any person registered with the RePEc Author Service can contribute information about oneself and others: institution and year where the terminal degree was obtained, advisor, and possibly students.

The collected data will be used in various ways. Currently, author profiles on IDEAS link back to relevant genealogy pages. The directory of institutions, EDIRC, has lists of alumni and their publications. In the future, when we have critical mass, we can use this data to properly rank young economists. Currently, we infer there start in the profession by dating their first publication. A graduation year would be more appropriate. Also, the genealogy data would also allow us to evaluate graduate departments.

Help make this service useful. You can add information by logging in using your RePEc Author Service credentials here. Thank you!


New CitEc features

September 24, 2012

In the past months we have added some new features to the Citations in Economics service:

References input service

Many documents in CitEc cannot be automatically processed due to a variety of reasons: they are not open access, not in PDF format or the PDF file can not be converted to text. Although some publishers provide us access to gated references, many are still missing. Often we get requests from authors asking why a citation to one of their papers is not included in CitEc. The answer is always the same: because the citing paper has not been processed. If this is your case, it is now possible to provide CitEc with the missing references and they will be processed. We ask, though, that all references from the citing paper be provided. Incomplete reference lists will not be considered. The lists of references and the contributor will be made public. The input form can be found here or from any IDEAS abstract page.

Add citation now

In some cases a paper cites a document available in RePEc but the system is not able to identify it as a RePEc item. For each reference not automatically linked by the system, the user may now add the handle of the cited document. All citations submitted through this feature are monitored to check if it is correct or not. A link to this form can be found from any IDEAS abstract page.

Citation profiles for authors

CitEc now provides citation profiles for authors. For each registered author in the RePEc Author Service, we provide a profile with her scientific production and the number of citations of each paper. Also we provide some indicators like the h-index and information about recent co-authors. For an example look at: http://citec.repec.org/p/z/pzi1.html. Note that this is work in progress, and the statistics on this page are not yet adjusted the way they are for the ranking statistics (versioning, self-citations).

New design for series pages

We have changed the format of the citations and production graphics. Also the papers bibliographic data is presented in a clearer way. An example at: http://citec.repec.org/s/2010/miewpaper.html

Included historical data for series pages

The time series for series citation data now goes back to 1990. Citations, document production and impact factor for all years is provided.

Use of persistent URLs

Now it is possible to access the citation data for authors and documents using short and persistent URLs like:, http://citec.repec.org/RePEc:mie:wpaper:382 or http://citec.repec.org/pdu7. To create such URLs simply add to http://citec.repec.org/ the paper/article handle or RePEc Author Service Short-ID.


OpenID authentication through RePEc

August 21, 2012

It is now possible to use RePEc Author Service credentials to log into some other websites using the OpenID schema. This means that users do not need to use separate user names and passwords for those websites.

OpenID uses a user’s web page to establish credentials, as long as the website participates in OpenID. The RePEc Author Service now does so, with the drawback that few users know their profile URL (for example: http://authors.repec.org/pro/pzi1/). For this reason, services using OpenID credentials through RePEc will typically request the user’s RePEc short-ID (for example: pzi1). The latter can be found on an author’s profile on EconPapers or IDEAS, or by using a RePEc short-ID lookup tool.

A typical authentication procedure goes as follows:

  1. The user is asked for a personal RePEc short-ID at a referring service.
  2. The service forwards this information to the RePEc Author Service, which shows the habitual log-in page.
  3. The user enters the usual RePEc Author Service credentials (email address and password).
  4. Upon success, the RePEc Author Service asks for confirmation that log-in should proceed at the referring service.
  5. Upon confirmation, the referring service obtains confirmation from the RePEc Author Service that this is the person with this short-ID.

Steps 2 and 5 are bypassed if the user has a live RePEc Author Service session. It should be noted that the RePEc Author Service does not communicate the email address or the password, only that the owner of the short-ID (and its corresponding web page) is indeed this person. The referring service is then free to use the short-ID in its own authentication.

Note that some people will not be able to use this authentication service right away. Indeed, their RePEc Author Service profile needs to be enabled for this. This is not the case for anybody who has not logged in the RePEc Author Service since late June 2012.

OpenID authentication through RePEc is currently in use for the maintenance of reading lists and publication compilations on IDEAS, as well as for the RePEc plagiarism committee. Other services that require authentication, tied to RePEc or not, will soon follow.


Linking with social media and page translation

June 26, 2012

We have noticed that material on RePEc is used quite heavily on social media, in particular Facebook, Twitter and Delicious. To make it easier, IDEAS now features on every page buttons that allow a user to quickly link with some services. Currently, the following options are available: Facebook, Twitter, Delicious, StumbleUpon, Google+ and Reddit. In addition, there is a button to print and one to email the link.

The code for all this was custom written to avoid using tracking cookies that are common with similar referral services. One consequence is that the email button will only work if an email client is installed on the computer. It will not work with Gmail, Hotmail, and other web-based email services.

In addition, Google Translate has been implemented as well, which should be able to translate any page you your language of choice, even when several languages are present. Of course, only the original version is guaranteed to be accurate. Note that this service uses a tracking cookie, but virtually everyone already has a Google cookie anyway.

EconPapers will soon implement the same features.
