"Jen Nia Mondo" - Author: John WELLS

The material was created in the early 70's with the goal of broadcasting it from student radio stations, which actually happened at the University of Essex, before the publication in book form. The style and the spirited contents of the lessons, which come in the form of a dialogue, reflect that mood. The materials became an amusing and attractive instructional tool. The grammar is concisely presented using short English explanations and relevant examples immediately after the lesson texts. The writing exercises mainly consist of translation exercises and fill-in-the-blanks drills. For clarification of the vocabulary, parallel with the text, there is a bilingual word list at the edge of the page, and at the end of the book there is a dictionary with an index of lesson numbers. The first book, in addition to the English version, also appeared in Icelandic, Italian, and Swedish versions. The English sound materials are good, with samples of speech. We can't say the same about the Italian version, which has strong national language accents. We don't have information about the other two languages. The teaching material is suitable for self-learners.

"Detektivu pri la krimo de Katrina" - Author: Katalin KOVÁTS

The exercises step by step help to understand and work through the reader Krimo de Katrina, the first book of the Katrina series, by Sten Johansson.
The exercise booklet has 4 or 5 various exercises for every chapter. By working the exercises, the readers can gain experience using the various important elements of basic grammar, e.g. the accusative, pronouns, prepositions, correlatives, etc, and at the same time learn geographical and historical facts. Last but not least, it's important that after reading and really understanding perhaps one's first book in Esperanto, one is much more interested to read more books in the language.
The exercises (prepared for the 2nd edition of the book) are usable in a course and for individual study. The solutions are provided to help check one's work.
Here is the first chapter in PDF format.

"La Krimo de Katrina" - Author: Sten JOHANSSON

The story is about young people from Sweden and Germany, with friendship and love affairs. This story, written in easy Esperanto, is suitable for those familiar with the most basic grammar and vocabulary. The plot moves forward smoothly... until the "criminal" ending! (But don't expect a horror story!) As in similar works by the author, each chapter introduces new language forms and structures. New words are clearly explained in Esperanto at the end of every chapter. At the end of the booklet, there are suggestions, statistics, and rankings of the words used.
The book can be easily used as reading material for beginners (after study of basic grammar), whether for individuals or for group reading.
It's worth reading and solving the special exercises, created for this book. See: Detektivu pri la krimo de Katrina.
The work La Krimo de Katrina is a prequel to Vojaĝo kun Katrina and Katrina malfruas, other easy stories by the same author.

The somewhat romantic story is about a young teacher and her students, the friendship between them, political injustices, a trip from Gotenburg to Bialystok, and last (but not least), use of Esperanto. The international language, on many occasions, appears as a natural and/or clever solution to communication problems.
The book is written in easy Esperanto. The chapters step by step introduce new forms and structures. Unfamiliar words are explained in Esperanto at the end of every chapter.
The book can be easily used as reading material for beginners (after study of basic grammar), whether for individuals or for group reading.
