 Dataset info
 
 The Greek Primary and Secondary school textbooks dataset is a set of 227 school books of Primary and Secondary Education. It contains all texts and all subjects taught at school, except of foreign language books, workbooks, and teachers' books. The texts were extracted from the official, public school textbook repository at https://ebooks.edu.gr/new/allcourses.php .
 
-The books have been cleaned programmatically with the aim of retaining the text from first to last page of interest to the student. Exercises, bibliography, and glossaries have been removed. The code used to clean the texts is accessible at glossAPI github repo. Due to the automatic nature of the cleaning the texts might still contain some of the above elements (exercises etc.), and chunks of text beyond those elements might be missing.
