Since 1997, RePEc services have found various ways of disseminating the bibliographic metadata collected with the RePEc projects. As the data and the types of data have expanded over the years, services were able to add more and more features, some of which are not well known. The purpose of this post is to highlight some of them. A broad introduction to RePEc services was recently posted here.
When a bibliographic item or an author is mentioned on Wikipedia with a link to a RePEc service, a link to the Wikpedia article in provided on the relevant IDEAS page.
The same applies to blog posts that have been identified through the EconAcademics.org. blog aggregator for economic research.
A large number of viewership statistics are available at LogEc. This includes statistics for individual papers and articles, authors, series and journals. For the latter, this includes total readership as well as most popular items within a series or journal. For authors, one can also find the most read authors by country.
All RePEc services offer search functions, But if you do not know what to look for, you can look at a random item.
Publishers provide all bibliographic metadata to RePEc. Sometimes, their data contains errors that prevents the publications to be indexed appropriately, if at all. This can be checked here.
On IDEAS, one can export bibliographic information in various formats for various lists: publications of an author, references of an item, citations of an item, and citations of an author.
It possible to track additions to author profiles, JEL code, series, and journals with MyIDEAS.
MyIDEAS also allows users to flag items they run across IDEAS and keep them in their account. They can then be annotated, sorted into folders and exported in various bibliographic formats.
There is a Facebook plug-in that allows you to display you last three publications. Install it from here. Update: I am told this functionality cannot be obtained on Facebook anymore.
One can obtain a compilation of the publications of all members of an institution. Find th link on the institution’s page at EDIRC, where there is also a link to the publication list of the institution’s alumni, if applicable.
You can also create a list of publications for a custom group of people. See the current lists or create your own here.
If you want to make public a reading list for a topic or a course syllabus, you can create this here.
A few editors have started to determine the most important works in their research area. See RePEc Biblio, where you can volunteer to contribute, too.
Economists are very interconnected through co-authorship. You can explore this co-authorship network at CollEc, where you can also find how far removed from each other any two economists are (“degrees of separation”).
An important part of RePEc is citation analysis. Unfortunately, this fails for some documents, either for technical reasons or because publishers do not furnish relevant data. One can help our citation project CitEc through this form.
RePEc tries to match different versions of the same work. The conditions are that 1) at least one co-authors has all versions in her RePEc profile, and 2) the titles are very similar. When the process fails, for example when the titles are different, users can help through this form
Matching citations to items listed in RePEc is a very complex process, for example because there are many citation formats and because authors do make mistakes in the references. When matches are too uncertain, authors can help. They should click on the “citation” link in their RePEc Author Service profile and accept or reject proposed matches.
A new project tracks where and when an economist got his final degree, and who his advisor was. The data collection is crowd-sourced, so you can participate in the data collection here as well. See the RePEc Genealogy. Collected data will soon be used to evaluate graduate programs.
Unfortunately, we have cases of plagiarism. When relevant authorities do not deal with such cases, afflicted authors can turn to the RePEc Plagiarism Committee, which evaluates cases and possibly names and shames them.
And finally, for economics departments and publishers that do not yet participate and index their publications in RePEc, instructions are available.
