The sales of dictionaries have been in decline for years and at the same time the number of visitors to our online dictionary has grown enormously. The decision to stop printing dictionaries was therefore based on a choice that had been made by our users.

Using Macmillan Dictionary Online is totally free, but you do need to have access to the Internet. Macmillan Dictionary Online is mobile optimised, which means that the site is easier to navigate on smaller screens like tablets or smartphones.
We understand that not everyone in the world enjoys good connectivity at the moment, but the overall picture is that access to the Internet is becoming increasingly widespread and this will further improve in the future.
There are many advantages to an online dictionary: the multimedia aspect, the ability to hyperlink words to aid the discovery of new ones and the ability to frequently update content instead of once every few years.
Another big advantage of the online dictionary is that it's not platform-specific so both Windows and Mac users can access the content. The online dictionary site is optimised for the most widely used browsers.
We recently launched several language games and downloadable language puzzles that are very good for polishing up your language skills. Such great resources simply aren't possible with paper dictionaries.
A big advantage of Macmillan Dictionary Online is that it's not platform-specific so both Windows and Mac users can freely access the content. Macmillan Dictionary Online is mobile optimised, which means that the site is easier to navigate on smaller screens like tablets or smartphones.
We have our weekly BuzzWord column, in which the author takes an in-depth look at interesting new language trends. We also have the Open Dictionary, a crowd-sourced dictionary which includes entries submitted by our users. In addition, we make several updates to the dictionary every year to ensure that its content is up to date.
No, we don't think they will. On the contrary, we feel that an online dictionary encourages exploration and offers greater opportunities for discovery. Because every word is hyperlinked, you're never more than a click away from a new definition, increasing the speed and ease with which you can browse and learn new words.
