In the Shafi'i Madhhab, in fact Islamic fiqh as a whole, one very significant contribution is undoubtedly Imam Nawawi's Minhaj al-Talibin. This work is written according to the Shafi'i Madhhab, one of the four schools of thought. The founder of this madhhab, Muhammad b. Idris al-Shafi'i (radyAllahu 'anhu), authored a large writing in the subject under the title Kitab al-Umm. And according to some, like Sayyid 'Alawi al-Saqqaf in al-Fawa'id al-Makkiyyah, his student Imam Muzani summarized Kitab al-Umm into a work under the title Mukhtasar al-Muzani.
Imam Muzani's Mukhtasar received a lot of attention, being elucidated on commentated on for years by the leading Islamic jurists of the time until it was commentated on by Imam al-Haramayn al-Juwayni in his magnum opus, Nihayat al-Matlab fi Dirayat al-Madhhab. A masterpiece work indeed. After Imam al-Haramayn, his student the famous Imam Abu Hamid al-Ghazzali, summarized Nihayat al-Matlab into a work under the title Basit, and then summarized that into Wasit, and then Wasit into Wajiz.
According to some, Imam Rafi'i took Ghazzali's Wajiz and summarized it into his Muharrar. While according to others, Muharrar is an independent work. And Muharrar is the work Imam Nawawi took and abridged under the title Minhaj al-Talibin.
And Minhaj al-Talibin serves as the central legal work in the Shafi'i Madhhab. Ibn Hajar commentated on it in his Tuhfat al-Muhtaj, a work relied on for the giving of fatwa. And this is what is printed in the margins of this particular edition.
Furthermore, this edition features the marginalia notes on Tuhfah from both 'Abd al-Hamid al-Sharwani and Ibn Qasim al-'Abbadi. Sharwani's feature on the top of the page above the line and Ibn Qasim's on the bottom.
This is the era 1938 print of Matba'ah Mustafa Muhammad, Cairo, Egypt. It still finds circulation through the means of reprints in the Arab World as do other earlier prints of Ibn Hajar's works.
