Using the RePEc search engines

January 24, 2020

RePEc seeks to enhance the dissemination of economics research. There are many ways to do this, and an important one is to provide search engines for literature searches. This post discusses two on them. Searching on RePEc provides many advantages over searching with your favorite web search engine: search are naturally limited to academic economics content and can be configured in many ways because RePEc has much more detailed information.

EconPapers

EconPapers is a popular site that allows to discover all RePEc content through browsing or searching. The advanced search page highlights all the fields that can be used to narrow the search: date, field (through JEL code), document type, online availability, and language. One can differentiate the search terms across author, keyword, and abstract fields. Boolean searches with logical operators are available and wild cards can be used on word stems. It is also possible to search within NEP reports if one is looking for a working paper within a specific field. A help page provide further hints and tricks for an efficient search.

EconPapers displays search results in a convenient way, showing the listing in a box and one can click on individual items to see the full content. Results can be sorted by date, relevance, or alphabetically by title.

IDEAS

IDEAS is another popular site with functionalities similar to EconPapers. Its search engine was recently improved. It offers similar fielded search with a few tricks that differentiate it from EconPapers. For example, word stemming is algorithmic, thus wildcards are not needed. Synonyms are used natively, reducing the need to think about them. One can search for AuthorOne AuthorTwo (Year), the typical way one cites in economics, and a match will most likely be displayed. A search from the listing of a journal of a working paper series limits the results to that serials. The same feature is available for JEL codes. The search page also offers separate searches for other item types in RePEc, such as registered authors and institutions.

Search results can be sorted by citation counts or a combination of criteria. In addition, on can save a search to MyIDEAS, which allows to go back to it easily later or get weekly email alerts about new search results. Individual search results can also be saved to one’s personal MyIDEAS bibliography with one click.


RePEc in 2019

January 4, 2020

2019 has been an interesting year. Indeed, while traffic has been on a long decline for the set of reporting RePEc services, there has been a major turnaround in 2019. For those services, we counted 5,821,298 full text downloads and 28,629,161 abstract views, numbers that are the highest since 2017 and 2013 respectively. We will see whether this trend will continue in 2020. A contributing factor may be the continuous improvements of the websites that drive most of this traffic. This blog will talk over the next year about how RePEc services distinguish themselves from other more generic services and thus are particularly useful for economists and the general public interested in economics.

Of course, this growth of traffic was likely also fuelled by an increase in content indexed by RePEc. We can highlight the following numbers:
87 new RePEc archives,
66,000 new working papers, with 200 new working paper series,
167,000 new journal articles, with 400 new journals,
for a total of almost a quarter million newly indexed works,
2,600 newly registered authors,
and 3,200 NEP reports.

Looking forward to 2020!


RePEc in December 2019

January 4, 2020

The big news of the month is that there are now over 3 million works indexed in RePEc. This achievement would never have been reached without the help of our over 2,000 RePEc archive maintainers. The latest ones to join this group were: Junior Scientific Researcher (Romania), Croatian Economic Association. We also counted 507,039 file downloads and 2,906,575 abstract views, Finally, the full list of the milestones we reached over last month is:

3,000,000 works listed
500,000 working papers with references
8,000 ranked institutions


3 million items indexed in RePEc

December 12, 2019

A few day ago, RePEc reached a major milestone by indexing over 3 million research items: journal articles, working papers (pre-prints), books, book chapters, and software components. The graph below, taken from the LogEc website and not yet featuring the December 2019 numbers, shows the evolution of the RePEc index since its start in 1997 (click on it to view a larger image).

This graph shows that RePEc content continues to grow relentlessly. With all major publishers participating in RePEc by now, the growth now comes much less from new archives but rather from the continuous growth within the over 2000 participating RePEc archives featuring over 5000 working paper series, 3500 journals, and more. As economists would say, we have shifted from the extensive margin to the intensive margin, which can explain a slight decrease in the growth rate over the last few years.

The first statistics at the end of January 1998 indicate an index with 51,984 entries. The first million was reached in January 2011, the second in December 2017, and the third now in December 2019. Only two years for the last million!

If your publishers or your local academic or policy institution still does not participate in RePEc, it can join by following these instructions, or you can upload your works as an individual contributor at MPRA.


RePEc in November 2019

December 4, 2019

November was remarkable for a significant push in new content. 10,000 new working papers and 32,000 new journal articles in a single month. In part, this was thanks to our new participating archives: Global Regional Review, Center for Open Science, Science Publications, Sapienza University of Rome. Also, we counted 607,140 file downloads and 3,805,447 abstract views, the latter being a record for a single month.

Finally, the milestones we reached:

100,000 book chapter abstract views in a single month
100,000 book abstract views in a single month (was in October 2019)


How to contribute data to CitEc

November 26, 2019

CitEc is the RePEc citation indexing service. CitEc extracts reference data from documents directly or from data about references provided by publishers. Then CitEc links references to find citations between documents available in RePEc. All data produced by CitEc is freely available. It is distributed to other RePEc services to enrich the services provided to researchers and authors. It is used to build citation profiles for registered authors, for working paper series and journals. I created CitEc in 1998. Nowadays, it contains over 41 million references and 14 million citations. This may be impressive numbers. But the data comes from 1.376.000 papers. Note that there are 2.737.000 downloable items in RePEc. Thus, I have been able to process only the 50% of the downloable items.

There is still a lot of work to do. You can help. Let’s see how.

1.- Providing references

One important approach to get references is to use the full text of documents. In many cases, we can extract that from the PDF files when we have them. However, PDFs are often behind tool gated portals. That is often due to economic issues like payment licenses. Sometimes it is due technical barriers, like the archive maintainer not providing an URL with direct access to the PDF file.

In these cases, you can help by submitting the full list of references cited. You do not need to be the author of the paper to submit the references. You may, for instance, submit references for a document that cites your work.

Thus, go ahead and use the web user input form. Thanks!

2.- Providing citations

Citations are relationships between two documents. Both the citing and the cited document must have a RePEc handle, thatis, be indexed in RePEc. The majority of citations are identified automatically by CitEc software. In addition, there are several ways to contribute citations to the database when the system has failed to find them.

A.- Register with the RePEc Author Service and use the search engine to add citations to your profile

B.- If you already know the paper which cites your work, follow the instructions in our FAQ (3.5)

C.- Otherwise, you can use the main CitEc search engine to look for the cited work in the references database. Just enter one author’s
surname and publication date for the cited work. You will get two types of results: citations and references. When you see a citation, CitEc has been able to match the reference to the cited document in RePEc. When you see a reference, CitEc has not been unable to find the cited document in RePEc. In some cases, the cited document is in RePEc but the system has not found it. You can help us to solve the problem by providing the link to the cited document. Just click on the “add citation now” link and give the handle of the cited document.
