I used to think that reference publishing was somewhat out of date; that nobody produces reference works nowadays, ever since Wikipedia took over the encyclopedia market.
But it is clear that reference publishing is not dead. It has changed, with digital delivery, and it has different requirements, but there are criteria for evaluating reference works. I will therefore add occasional posts about reference works and where they succeed or, in my opinion, fail. These may be print or digital works, but in many cases the principle is the same.
For the principles on which these reference ideas are based, see my Top Ten tips on reference publishing .
