asSalaamu Alaikum,
Ma’ariful Qur’an is the acclaimed Tafseer written by Shaykh Mufti Muhammad Shafi Usmani (ra).
Many of you may already be familiar with the online scans of this Tafseer (English version & original Urdu). The latter website also has partial audio recordings of Ma’ariful Qur’an in English and the complete audio recording in Urdu.
For English readers, Ma’ariful Qur’an is also available at the following site in a format that is much easier to navigate and read, with a scroll-down option on the left:
Ma’āriful Qur’an – easy to navigate format
Another upload of Ma’āriful Qur’an (although incomplete) in html format: Ma’āriful Qur’an html
at-Tahawi 
Jazakumullahukhairan,
The following resource may also be of use. http://www.classicalislamgroup.com/index.php?view=tafseer
it allows copy/paste, as the PDF’s have been converted into html format.
Jazakallah Khair for sharing such a good resource.
JazakAllaahu khayr! this is awesome!
Any information about which edition of Maulana Thanawi’s tafsir, Bayan al-Quran, is best?
thank you for this
JazakAllah khayr a million times over!
Please add the first 61 pages as well. Please, please, please! Your site enables me to place links inside my new translation of the Quran which is in my mother tongue the “Afrikaans”-language of South Africa. The fact that the first 61 pages is absent, disables my whole effort because these pages contains valuable information which I want to place links to. ☺
