Abstract: Online research tools allow researchers to embrace online research communities and establish an online presence. An online presence implies e-visibility which embodies online visibility, discoverability and accessibility. In December 2014 an e-visibility survey was conducted on environmental science researchers at Unisa to determine their perceived e-visibility. The results indicate that the majority of researchers are emerging researchers with an average age of 40; with a master’s degree and they are employed at lecturer level. The majority of participants have online research e-profiles and they prefer e-profiling, using online research social networking tools. In addition, the majority prefer free resources (Google Scholar) to fee-based citation resources (Scopus and Web of Science) in order to ascertain their online research presence and traditional research impact. The low percentage of profiling, using traditional fee-based citation resources translates into low online visibility. A low percentage of researchers participated in self-archiving their research output to repositories is reported; this has an impact on online research discoverability and accessibility and suggests low discoverability and accessibility of online research. The development of an e-visibility strategy would allow the enhancement of e-visibility by increasing online research visibility, discoverability and accessibility.
