My grandfather fought in the Spanish Civil War - can you find any information about him in your collections?
A Guide to the Spanish Civil War Collections provides a survey of all primary source materials on the Spanish Civil War at the IISH. This guide is an index to collections consisting of hundreds of files and thousands of documents. Unfortunately, due to a lack of personnel, the IISH Reading Room staff is in no position to search for personal information or documentation about individuals. If you wish to consult the archival materials you're welcome in the Reading Room. If, after consulting the inventories, you've found documents of interest, it is possible to order some reproductions, for research purposes only. See Reproductions for procedure and rates. The inventory to Confederación Nacional del Trabajo papers is online available. It is a large collection and holds no index on names. Unfortunately, we lack the staff to search for these documents.
The CNT papers have been microfilmed, the originals are very fragile. You're welcome to consult the archive in the Reading Room and make copies yourself from films.
