These files and other resources are from my old web site (pre-2010). They remain in place (i.e. the original URLs are unchanged).
Any work related to this is over, and is unlikely to be revived.

Digital editions of problem books
Some of these problem books have since become available as digital scans, which are always preferrable to edited texts: no matter how carefully they were produced, there are sure to be errors. If such sources are known, and are generally available, links to them have been provided.
Most of the problems are available as PBI files, a very simple text-based ‘card-oriented’ problem transcription format. These are, however, transcriptions of the original sources, used as starting points for the books; they do not contain all information present in the PDF editions.
Note: Books availble from HathiTrust can be read on-line, but cannot always be downloaded freely. However, check the menu for ‘Get This Item’: if it has a ‘Find at Google Books’ entry you may be able to download it, even if Hathi itself does not allow that. (This seems to happen when Google is asked to revise its copyright classification for old texts, and decides that it actually is publica domain.)
All local problem books and their PBI files are free to be used in any way at all. Books on external sites may have separate conditions for use.
Additional PBI files
In addition to the PBI files used as starting points for the problem books listed above, I also made some additional PBI files available. The file format is documented here.
|Schachzeitung der Berliner Schachgesellschaft, 1846–1849||ZIP(PBI)|
|Schachzeitung der Berliner Schachgesellschaft, 1850–1859||ZIP(PBI)|
|Schachzeitung der Berliner Schachgesellschaft, 1860–1870||ZIP(PBI)|
|Deutsche Schachzeitung, 1880–1889||ZIP(PBI)|
I’m considering adding new material to this list (or to a new list), and the options that are available today.
