.. Computer password

Say, before surfing the web you should read the microfilms.

And see the ghosts?

Right. There's someone else who would like to use the computer.

Talk to Yeats (in the reading room), then talk to Crowley (in the microfilm room).

Great, now you can go and ask around if someone knows the admin password.

Ask Raxa, in the reading room. She will tell you the password.

Use the password on the computer and talk to Crowley. Crowley will now browse some naughty internet.
