The PLAID database is not yet publicly available. 

The National Science Foundation (NSF) has given the PLAID project a grant that will allow us to expand the current data and eventually make it available to the public. The end product will be a web-based data query system similar to those currently in use by the World Bank, OECD, and Penn World Tables. As per our agreement with the NSF, we expect the data to become fully public by 2008.  If you would like access to the PLAID database prior to its public release, we will entertain offers for collaboration or data swaps.  Please contact one or all of the PIs for details.

Replication data sets are available for journal editors and reviewers upon request.  If you require a replication data set, please contact the authors directly.

Methodology for both the compilation of the PLAID database and individual sector coding is available in the PLAID Codebook.
