I've recently had cause to look up some US macroeconomic data for the 1930s, and was reminded of something: I never got around to converting all the NBER Macrohistory data to gretl database format. That's now corrected: there are gretl databases for all 16 "chapters" on our database server. To see what's there: http://www.nber.org/databases/macrohistory/contents/ and "/File/databases/on database server" in gretl. In constructing the gretl files I used the ".db" versions of the individual NBER series. This is a plain text format with metadata in a reasonably simple format. However, I skipped some of the .db files that seemed broken. This was for two main reasons: * In some cases the number of observations is not consistent with the reported starting and ending dates and frequency, so I don't know how to place the data on the timeline. * In some cases there's no definition or description of the series, just an NBER ID number, and I can't find a table that tells me what these numbers mean. There are lots of series, and these two problems exclude only a small proportion of them. Allin
