Terrae Incognitae

Terrae Incognitae is an interdisciplinary, peer-reviewed journal published for the Society for the History of Discoveries. The aim is to examine the history and impact of geographic exploration and cross-cultural interaction around the globe prior to the modern era. Each issue includes an expansive book review section. Recent articles have ranged from the use of DNA technology to track the movement of chickens and thus populations in pre-historic Oceania to the role of the Order of Christ in furthering 16th-century Portuguese expansion; from the significance of inter-cultural adoption or rejection of clothing for understanding cross-cultural interaction to Marco Polo’s influence on cartography. Terrae Incognitae accepts contributions relating to geographic exploration and its impact from all chronologies before the modern era and relating to any part of the globe. The journal welcomes comparative and interdisciplinary studies as well as those focused on a particular time or place. The origin of geographic discovery and exploration is lost to the mist of time—perhaps when an early hominid went searching for game and discovered another group of humans. Geographic discovery is about more than the moment of discovery, however. It is about theoretical geography put into practice; it is about bankrolling expeditions, whether through the investment of wealthy widows, old age pensions, financiers, or governments; it is about maps and mapmakers; it is about diplomats, missionaries, explorers, scallywags and pirates, naturalists, and merchant-adventurers. Geographic discovery is about people broadening their horizons, encountering one another for the first time, struggling to understand a foreign culture, and braving the unknown in search of a new destiny.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
