There are 112 pages in the attached pdf file. Each page contains one section of Epicurus' core texts (the three letters and Principal Doctrines) as per Diogenes Laertius' notation and is marked as such at the top.
Every page has four sections. Epicurus' words in Greek are followed by three translations: Yonge's, Hicks' and Bailey's. I think such arrangement can enhance the study of the philosophy by increased understanding of each passage.
I know there are more modern translations available but I included only those translations which are complete (i.e. all core texts are translated) and are in public domain. This way, the attached file can be freely distributed and used without any constraints.
This is an initial version and most likely contains some errors. Please let me know if you see something in need of correction or you have an idea how the file can be improved. I'll do what I can to make it better.
Have a blast studying!
