Orunodoi or Arunodoi (Assamese: অৰুণোদই, English: "Sunrise") was the first Assamese-language magazine published monthly from Sibsagar, Assam, in 1846.

The Assamese people got to know about the western world only through this magazine, which opened the gate to the modern literacy in Assam.

[2][3] Orunodoi was founded by Dr. Nathan Brown[4] and was first published in January 1846, printed by the Baptist Missionary Press in Sibsagar.

The tag line for the magazine was, "The Orunodoi, monthly paper, devoted to religion, science and general intelligence".

Notable among these publications are Kashinath Tamuly Phukan's Asom Buranji (1842) and Anandaram Dhekial Phukan's Axomiya Lorar Mitro (1849) and A Few Remarks on the Assamese Language and on Vernacular Education (1855), Bronson's A Spelling Book and Vocabulary in English, Assamese, Singpho and Naga (1839)[6] printed at the Mission Press in Sibsagar.

It (Orunodoi) explained global geography and gave descriptions of the night sky with its stars and planets.

The mind of the readers was thus treated to a very much rich fare.Oliver Thomas Cutter was born on 19 March 1811 at Lexington, Massachusetts, USA.

Looking for a more hygienic and conducive place for work, Brown shifted to Sibsagar in 1841, while Cutter continued at Joypur superintending the operations of the presses under his care.

However tribal protest at the conversion activities carried on by the missionaries soon made Joypur an extremely difficult place to work in and also inconvenient for printing due to threats from the locals, for which Cutter had to hide his presses.

Finally, in 1843 Cutter moved to Sibsagar and established the printing press along the bank of the Dikhow River near the cantonment.

The Asom Year Book 2008 acknowledges Cutter, Brown and Bronson among the six foreigners (along with Edward Gait, John Berry White and Charles Alexander Bruce) who rendered benevolent service for Assam.

While Nathan Brown and Miles Bronson are well known for their contributions, however, a lesser known junior missionary, the Reverend William Ward, played an important role in propagating the printing of the book in Assam.

She revised the missionary Oliver Cutter's wife Harriet Cutter's work Vocabulary and Phrases in English and Assamese (1841) and added many new entries, bringing the total to about 4500 entries, published as Brief Vocabulary in English and Assamese with Rudimentary Exercises in 1864 by Mission Press, Sibsagar.
