The main objective of this work is to find out the general scholarly usage of this top-level domain. In particular, the following three questions are pursued: usage (number of web domains registered with the dot-science), purpose (main function and category of websites linked to these web domains), and impact (websites' visibility and authority). To do this, 13,900 domain names were gathered through ICANN's Domain Name Registration Data Lookup database.

As regards primary academic-related dot-science web domain categories, 1,175 (8.5 web domains registered) were found, mainly personal academic websites (342 web domains), blogs (261) and research groups (133).
