When you click on Download in the menu, you will be able to download a DOCX format version of the dictionary. This format allows you to read the dictionary on your computer as if you were reading a copy of the print edition. It is an exact duplicate what is available on this web dictionary, but as a soft copy. Once you have downloaded it you can read the dictionary without being connected to the internet.
You can also print out parts of the dictionary if you have a printer.
