City directories list names, professions, addresses of individuals, as well as many business ads. The city directories are excellent for genealogical research because you can trace the home addresses and professions of your family members beginning in the late 19th century, through the 21st century.
City directories were first published in 1869 and produced intermittently in the 1870's, 1880's. and 1890's. From 1900 onward, city directories were produced annually until 1942, where it was suspended between the years 1942-1947. Publication of the city directories resumed in 1947 and have been published continuously ever since.
Prior to 1954, all the city directories published included the islands of Hawaii, Maui, Kauai, Molokai, and Lanai. From 1954 onward, the city directories for these islands were combined into a separate volume and published.
