For performance rights, you must license the show. Do not just print a PDF. Contact (often managed through Lasalle College of the Arts or the publisher, Epigram). They will provide a licensed, watermarked PDF specifically for your production after you pay royalties.
While free PDF versions may circulate on student forums or file-sharing sites (like Scribd or Academia.edu), these are almost always unauthorized scans. Using these for performance is copyright infringement. The play is still very much under copyright protection. emily of emerald hill script pdf
