The data show that till well into the 1960s, the average article published in the APSR was solo-authored. Today, co-authored papers are the norm.
Over the past 100 or so years, article length has shown marked variability. There is a marked see-saw pattern in the average length of the article, but unlike top economics journals we don't see a marked trend towards longer articles. It is very likely, however, that the length of online appendices has grown substantially.
Get the (Meta) Data
All the data are from journals published by the Cambridge University Press (CUP). CUP has a single publishing platform for all its journals with the link differing only by 'JID'. For instance, to scrape meta data and abstract for all APSR articles from CUP, use (http://journals.cambridge.org/action/displayBackIssues?jid=PSR. The JIDs for various journals are easily found. They can also be scraped from the CUP page listing all the journals that it publishes.
To scrape the data, use get_data.py. The script depends on
urllib2. To run the script,
- Name of the output file. Specify
FINAL_OUTPUT_FILEon line 11 of get_data.py.
- Column names. Specify
HEADERon Line 18 of get_data.py.
Note: The script allows for interruption. If interrupted, it will restart from where it stopped. And it will append the results to the existing output file.
Each row in the csv is a separate article. And the columns are:
- 10 colums e.g author1, institution1, etc, ...,author1, institution1
