Many People are searching in the net to find Islamic Shia books. There are some good websites which put many many valuable books. I collect some more important ones of them and put it here:
1. al-islam.org: the biggest Shia Library
2. Tebyan.net: One of the most valuable and comprehensive Islamic library
4. eimaan.co.uk: This site ships from UK has an up-to-date selection including some unique gift items and DVD/CD offerings. The overseas shipping is compensated for by the selection.
5. Seyed Mujtaba Musavi Lari: You can download or request free copies of Musavi Lari’s excellent works in many languages.
1. Imam Al-Khoei Online Book Store: This is the online catalog of the Al-Khoei Center in New York with English titles, as well as Arabic, Urdu, and Farsi. Cheaper prices can sometimes be found elsewhere, so it pays to shop around. But this site has a strong selection that is regularly updated, the best search options, fast shipping, and interactive features such as reviews by readers and updates. You can also make secure donations to Shia Islamic charity needs from the store just as you would purchase a book.
2. Mehrab Publisher: This website is based in Canada. It has a good selection that includes some titles rarely seen or unable elsewhere. A few nice features are that you can add multiple items from a page to your cart at once, you can easily convert currency, and you can pay conveniently by PayPal. It is a little harder to search than some sites but worth spending the time.
3. Ansariyan Publication: The ultra-ubiquitous publisher ships from Iran, so to use this site you have to be willing to tolerate shipping times counted in months rather than days or weeks. It has a very large selection in a variety of languages, including English, Arabic, Urdu, Farsi, French, Azerbaijani, Turkish, Russian, Tajikistani, Spanish, German and few others.
And here are the runners-up: these sites may be less appealing due to lower selection, increased shipping costs or delays, or poorly functioning websites.
4. Al-Itrah Foundation: Appears modeled after Khoei.org in design, based in Dar e Salaam, Tanzania. Good prices, but that will be countered by shipping costs and time. Descriptions of books lacking, yet has a good selection.
5. Shia Book Shop: This site is based in Pakistan, books in Urdu only, payment in Rupees.
