Finally!

When I started teaching university nearly thirty years ago, the biggest headache I had was securing adequate copies of the text books I needed–many of which were out of print and only available in dwindling secondhand supplies. As personal computers became available, I always felt that the most logical use for them was to get rid of cumbersome, expensive and ephemeral texts in favour of electronic versions.

And now they've finally done it after only a breathtaking brief third of a century.

At this rate, they'll have gas lighting in no time.
