content: This series contains records of Tyrrell's career as both an engineer and a writer. His engineering records consist of employment and reference letters, lists of his engagements and the structures he designed, and many examples of advertisements (pamphlets, cards, announcements) created for his services as engineer in the multiple companies he worked for or founded. His publishing records include multiple copies of book reviews, personal endorsements, publicity material (advertising pamphlets, order forms, flyers), printing costs/profits/royalties for his books, and proof of copyright on his books from the Library of Congress. Legal and financial records mostly consist of legal claims filed against one publisher and several firms for which he did contract work, for breach of contract or lack of payment, as well as many returned (bad) checks from his time with the American Estimating Co.
