A contemporary review in ''The New York Times'' read:

... the book that literally never does grow old, that has a concise, authoritative statement on the memorable event of yesterday as well as on the event that occurred thousands of years ago; the book that is never finished, and that nevertheless has the latest word on pretty much any subject regarding which immediate information is desired, seems very much like the wild and insubstantial dream of some overworked press agent, were it not that the thing has actually been accomplished, that the book in question really does exist ...

The first edition of ''Nelson's Encyclopaedia'' was published in 1904 with a conventional binding.
