English-Esperanto (the Step-Theme-Arranged Learner's Dictionary, Steps 1 - 4)
It includes up to 6000 essential words and phrases belonging to the levels from Beginner to Intermediate. The entries are divided into 150 vocabulary themes as well as 4 learning steps. They are arranged by steps and then by themes‚ not by the alphabet.
The book is intended to help you learn this language step by step but can also be applied for translating or entertaining. You may use it separately or as an additional tool for any suited educational course.
The Multi Linguis Project is based on the Wiktionary corpus. The database of the Learner's Dictionaries includes 9 000 lemmas (words and phrases)‚ their translations into many languages as well as transcriptions‚ transliterations and grammar information.
All these lemmas are divided into 6 learning steps of 1500 entries each (corresponding to the levels A1 - B2 CEFR) and also 150 vocabulary themes grouped in 30 super themes. They can be arranged by themes‚ steps‚ parts of speech or keywords‚ but never by the alphabet.
Different types of dictionaries are offered for the same language. They 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 70 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).
