We have made available a number of files, some of which have been mentioned in the text. These can all be found at ftp.liv.ac.uk in the directory ∼ftp/pub/genus2 by anonymous ftp. You should first type:

ftp ftp.liv.ac.uk

and then login using anonymous as your name, and your e-mail address as your password. Then type:

cd ∼ftp/pub/genus2

which will take you to the correct directory. Once you have further changed to the desired subdirectory, then the standard command:

get filename

will copy the file filename to your local directory.

The current directory structure is as follows. In addition to the following files, there is also a file README in each directory, describing the contents of that directory. These should be read to check for any changes recently made to the directory. Please send any questions about these files to: evflynn@liv.ac.uk preferably with the subject header genus 2 ftp files.
