Hello! I will answer your questions honestly: I have 10 years of experience with academic research as well as writing. I have been extensively using the academic databases such as Scopus, Elsevier, etc. What you need I to do I do almost every day: finding citations, looking for papers, etc. I have not worked with EndNote before but I think it would not be a problem to learn its features. Th bigger problem would be to acquire the software package but I hope you provide it.
