As a topic for this conference I chose the first Romanian Encyclopedia, a luxury edition for those times, published in Sibiu in three volumes during “two centuries”: the first volume appeared in 1898, the second – in 1900, and the last – in 1904. This old and rare book is found in Special Collections of the Central Library. The volume was published with the support of the Association for Romanian Literature and the Culture of the Romanian People, edited by Dr. Diaconovich. The first Romanian Encyclopedia is an exceptional edition with an enviable informational volume, a true jewel of cultural and spiritual heritage. Certainly, several hundred scientists, scholars, writers, historians, lawyers, engineers, etc., from all fields of human activity and many countries of the world, have contributed to this titanic work. We will not be wrong if we affirm that all the knowledge of mankind until 1905 was included on these few thousand pages; the work being well located in Romania and in the entire Romanian cultural space.
