repec 0.0.1rc3

Download RePEc database

RePEc Database Manager

Download, cleanup, and somewhat structure the RePEc dataset into an SQLite database.

Quick Start

Install repec.

pip install repec

Initialize database repec.db and update urls.

repec init
repec update --repec

Update listings of selected journals, e.g. JF, JFE, RFS.

repec update --listings-of-handle repec:bla:jfinan
repec update --listings-of-handle repec:eee:jfinec
repec update --listings-of-handle repec:oup:rfinst

Download papers.

repec update --papers

Export bibliography (for selected journals).

repec export-bib --handle repec:eee:jfinec

Database

The SQLite database will contain the following tables.

Table	Description
repec	A list of ReDIF files from RePEc FTP.
series	Content of ReDIF files from RePEc FTP.
remotes	A list of URLs that host RePEc data.
listings	File listings from the sites in remotes.
papers	Titles, abstracts, etc. of economic papers.
authors	Author names.
jel	JEL codes.
papers_jel	Correspondence between papers and jel.

Non-standard Dependencies

The scripts use cld2-cffi for automatic language detection, and curl for downloading from FTP sites. curl is used instead of requests, because requests cannot handle some of the FTP sites out there.

Update Process

repec update

First, the names of all the available ReDIF files are downloaded from the RePEc FTP and saved in table repec.

Second, all the files from table repec are downloaded from the RePEc FTP and are used to fill in table series. Among other data, table series will contain URLs where the data on particular series can be found. Unique URLs are then saved in table remotes.

Third, all unique URLs will be visited to collect the listings of the final ReDIF documents. These listings are saved in table listings.

Fourth, all the files from table listings are downloaded, processed, and saved in tables papers, authors, and papers_jel.

If an update is interrupted during the last stage, you can run

repec update --papers

and the update should resume from where it has stopped.

Incremental updates are currently not supported, however it is possible to perform a full update on an existing database. Paper records that are obsolete, i.e. those that can no longer be reached from the initial list of series from the RePEc FTP, are not pruned. This is done on purpose as on some days some participating websites work, and on other days they don't.

Downloaded records are saved as is in papers.redif (z-compressed). Additionally, the records are cleaned up and partially destructured into the respective fields. The cleanup steps include, among other:

• stripping html tags;
• language auto-detection (using cld2-cffi);
• jel codes extraction.
