* Known problems and future improvements

- There are numerous errors in the annotation resulting in
  inconsistencies. In particular changes in the part-of-speech 
  annotation may not be reflected in the syntactic annotation, 
  leading to e.g. head-rule violations.

- Inconsistent treatment of end-of-line hyphenation in tokens.

- Sources are only provided in the form "scrubbed" texts, not any
  html/pdf files.

- Annotation guidelines missing.
