This directory shows commonly requested meta-data for the 
NBER working paper series in tab or pipe delimited UTF-8 or 
Stata .dta formats suitable for analysis by statistical or 
general purpose software. Formats for bibliographic software 
are linked from 

  http://www.nber.org/policies.html

All of these files should update automatically each week.

For the character files the first column is always the working 
paper number, then a tab, then the listed variable. The first 
row has variable names.

File names and variables for the pipe delimited versions:

abs.txt       abstract
date.txt      issue date
jel.txt       JEL codes (multiple rows per paper)
prog.txt      NBER program names (multile rows per paper)
auth.txt      author code (first_last) (multiple rows per paper 
              for multiple authors)
auths.txt     authors, (comma delimited for multiple authors)
title.txt     Title
published.txt Book or Journal Publication information 

There is also ref.txt which combines paper number, author, title 
and issue date in a single line like a journal reference.

Stata versions are in ./dta and tab versions in ./tsv.

Working paper numbers have 4 or 5 digits and usually begin with 
a "w". However, in years past the prefix letter could be an "h" 
(for historical) or a "t" (for technical).

The published.txt file shows where working papers were 
eventually published. It is not comprehensive. It combines 
information from authors, Crossref, RePEc and online vitae and 
journal names may vary by source.

Please call if you need assistance.
