Looking For Litrec Dataset (Used In Book Recommendation Systems)

Hi everyone.

I am looking for Litrec dataset containing data on 1927 users who rated 3710 literary works. The dataset is used in some papers related to book recommendation systems. Here are the most notable ones:

H Alharthi et al., 2019, Study of linguistic features incorporated in a literary book recommender system H Alharthi et al., 2018, Authorship Identification for Literary Book Recommendations P. C Vaz et al., 2012, Improving a hybrid literary book recommendation system through author ranking

I have spent hours googling for the dataset, yet I have not found it. I would really appreciate it if you could help me access the dataset.

I really appreciate any help you can provide.
