The Multi Linguis Project is based on the Wiktionary corpus. The database of the Survival Dictionaries includes 999 lemmas (words and phrases)‚ their translations into many languages‚ transcriptions, transliterations and grammar information.
The sets of dictionaries are designed in an original way to be convenient and efficient. All of them are available in both pdf and mobile formats (epub and mobi).
Multi Linguis is presently able to publish such books for more than 200 languages. It's planned to improve them and increase their number.

Note: Because of the source, up to 3% of translations may be improper. Some expected entries have no translation so they were left empty (in pdf) or omitted (in epub and mobi).
