SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

A proud tradition
Endeavour, established in 1942, has, over its long and proud history, developed into one of the leading journals in the history and philosophy of science. Endeavour publishes high-quality articles on a wide array of scientific topics from ancient to modern, across all disciplines. It serves as a critical forum for the interdisciplinary exploration and evaluation of natural knowledge and its development throughout history. Each issue contains lavish color and black-and-white illustrations. This makes Endeavour an ideal destination for history and philosophy of science articles with a strong visual component.
Endeavour presents the history and philosophy of science in a clear and accessible manner, ensuring the journal is a valuable tool for historians, philosophers, practicing scientists, and general readers. To enable it to have the broadest coverage possible, Endeavour features four types of articles:
-Research articles are concise, fully referenced, and beautifully illustrated with high quality reproductions of the most important source material.
-In Vivo articles will illustrate the rich and numerous connections between historical and philosophical scholarship and matters of current public interest, and provide rich, readable explanations of important current events from historical and philosophical perspectives.
-Book Reviews and Commentaries provide a picture of the rapidly growing history of science discipline. Written by both established and emerging scholars, our reviews provide a vibrant overview of the latest publications and media in the history and philosophy of science.
-Lost and Found Pieces are playful and creative short essays which focus on objects, theories, tools, and methods that have been significant to science but underappreciated by collective memory.
