The collection's correspondence is organized into subseries for letters written by Dwarkadas and those written by other people (largely to Dwarkadas). Dwarkadas' letters (1918-1965, undated) are virtually all business correspondence, and discuss national and global politics (especially Indian independence and the Second World War), the status of labor organizations, and Dwarkadas' work with the Bombay Millowner's Association. Despite the professional nature of these letters, they reveal the warm relationships that Dwarkadas had with many of his peers in politics and business. To a large extent, the letters written by Dwarkadas are addressed to the same individuals whose correspondence makes up the next subseries (though there are a great number of letters in this series addressed to B. Shiva Rao in particular).

Some of the correspondence written to Dwarkadas, David Pole, and others (1914-1965, undated) strikes a more casual tone than Dwarkadas' own letters, though for the most part, these papers deal with the same subjects as those of the previous subseries. The largest files contain the letters of C. P. Ramaswami Iyer, Annie Besant, David Graham Pole, B. Shiva Rao and P. K. Telang. The files for Clement Attlee, M. Katherine Davis, Maryam (Ruttie) Jinnah, George Lansbury and Tej Bahadur Sapru, are smaller but not insignificant in size. Letters between Dwarkadas and Besant relate mostly to the Theosophical Society and to politics, but they also reveal how close these two figures were. The same can be said for the letters from Ruttie Jinnah, the wife of Muhammed Ali Jinnah and a dear friend of Dwarkadas'. The letters from M. Katherine Davis primarily concern her and Dwarkadas' involvement in philanthropic organizations, specifically the Children's Aid Society. Other noteworthy documents in this part of the collection include a few notes from Mahatma Gandhi (along with copies of a letter in which he explains his belief in celibacy), several short dispatches from Muhammad Ali Jinnah, and a slightly larger set of letters from Jawaharlal Nehru. In most instances, letters written by secretaries on behalf of their employer are filed under that employer's name.

Researchers will find Dwarkadas' letters to editors in Series II. Writings by Dwarkadas.

This series contains writings by Dwarkadas, including letters to the editor of newspapers such as the Times of India, the Bombay Sentinel, and the Bombay Chronicle (1924-1962, undated). These letters mainly call attention to social issues like housing deficiencies, prostitution, and bad labor conditions in coal mines, or provide Dwarkadas' opinions on world politics and diplomacy. Researchers will also find the drafted table of contents and manuscript for the second volume India's Fight for Freedom: an Eyewitness Story, Dwarkadas' account of the independence movement from 1938 to 1964, which appears not to have gone to press (though the first volume was published by Popular Prakashan in 1966). Some isolated chapter manuscripts, outlines and notes for India's Fight for Freedom, Ruttie Jinnah: the Story of a Great Friendship and perhaps other of Dwarkadas' published works are also included. Passages of text for the blurbs and cover pages of Dwarkadas' books exist, along with some copies of reviews of his literary work. These papers succinctly present biographical and autobiographical information about Dwarkadas. In 1946, Dwarkadas traveled to the United States for six months as a guest of the State Department to meet with labor leaders in this country. His journal entries and schedules from certain points in this trip are included in box 9, folder 12, along with a few itineraries from later business trips (1946-1955).

Between 1921 and 1962, Dwarkadas often recorded his interpretations of the state of Indian politics and his impressions of current events. These diary entries, titled "Personal observations and news" by Dwarkadas, provide detailed, honest, and relatively unfiltered information (or, sometimes, speculation) about Indian politics and politicians at several critical points in the country's twentieth century history. The accounts seem to be for Dwarkadas' personal reference (most are marked "confidential" or "most confidential"), though some copies of his radio broadcasts, lectures, and articles on politics are also included.

Dwarkadas' interviews with figures in Indian politics, typically in note form or summarized, are included in this series (1937-1962, undated). Some individuals interviewed on multiple occasions are Yashwantrao Chavan, Morarji Desai, Mahatma Gandhi, V. V. Giri, Muhammad Ali Jinnah, B. G. Kher, J. B. Kripalani, Kanaiyalal Maneklal Munshi, Jawaharlal Nehru and Vallabhbhai Patel, though conversations with many other people are also recorded. In some of these accounts of recalled conversations, Dwarkadas inserts post facto opinions or commentary.

Documents from Dwarkadas' involvement in labor organization and philanthropy comprise this series. The reports, proposals and meeting minutes relating to labor business convey information about disputes, negotiations, workers' strikes, and trade unions. Other papers in this series deal with the working conditions in factories and textile mills, and the social services (or lack thereof) available to low-wage laborers, such as healthcare and childcare. While some of these papers are relatively broad (for example, reports on India's general economic environment) a considerable number relate specifically to labor in Bombay's textile mills.

This last series in the collection contains writings by other individuals and organizations. The papers of the Bombay Children's Aid Society provide the meeting minutes of the provisional committee, some financial documents, and reports (usually monthly) of new "cases," that is, children who came under the purview of the Society on account of destitution or petty criminality, and were subsequently placed into the Umarkhadi Chilren's home, a boarding school, or some other institution. David Graham Pole's writings, quite abundant, report on industrial activity in India, relations between India and Great Britain, and general memoranda on Indian economic, political and social practices (a journal detailing one of Pole's trips to India is also included). The meeting minutes of the Bombay Prostitution Committee present the organization's research on prostitution (including data tables giving the number, location and size of brothels in the city) and their plans for gradually abolishing the practice. The several bulletins and manifestos of the Quit India movement urge protest and civic disobedience on the part of Indian workers, and request the withdrawal of the British from the country, a general sentiment echoed in a speech by Annie Besant, included in the next file. The few writings by Iyer relate mostly to the Children's Aid Society and the region of Travancore, and the "private and confidential" reports of the Advisory Committee on Imperial Questions discuss plans for Indian independent sovereignty. The files on Mill Affairs and the Industrial Disputes Committee contain labor agreements and regulations for the mills, and Rao's writings consist of four documents on the topics of Indian legislature and governmental organization. Documentation of the governments of Bombay and India (before and after independence) consist of meeting minutes, reports, budgets, bills, acts and information about some politicians. The writings by other authors or agencies are filed alphabetically, and for the most part concern the same topics discussed above (including labor conditions, philanthropic concerns, and social welfare programs) along with a quantity of speeches delivered by various dignitaries.
