All files are in PDF format. Works with Latin alphabets are text-searchable within the limits of the Optical Character Recognition (OCR) process used to turn scanned images into searchable text. In other words, the search accuracy, though generally high, is not guaranteed to be 100%. Non-Latin alphabets such as Arabic are not searchable."
