The Pop Up Oxford World Encyclopedia from iFinger Ltd has some room for improvement. One standout feature allows you to hover your cursor over a word and then the definition will popup if it is located in the software.

This product is lacking most of the features that make good encyclopedia software. Every single word that we typed into this program came up with an error for the search result.

The product is designed to run in sync with other programs and provide definitions to words.

The support and help documentation is non-existent; we clicked on the help documentation and received a 404 error.

Overall, the Pop-up Oxford World Encyclopedia is a poor product. For $3 more, you can purchase Encyclopedia Britannica's Standard.
