Suffering from a scarcity of Arabic scientific content on the Internet and finding it difficult to obtain Arabic studies and books from reliable sources without spending hours sorting search results? Don't have an account on university digital repositories? You may not pay a download fee for each search. I found you an Arabic alternative that searches in many Arab and foreign universities' repositories open with the support of Google and the results are direct and from reference sources and complete files for letters research and books.
