Posted below is an annotated listing of nine key sources on urban and transportation planning for my prospective concentration. I compiled these sources through a combination of preexisting exposure (as in the case of The Death and Life of Great American Cities and Crabgrass Frontier, two sources which are both informative and historiographically important) and a broad search for relevant sources through Google Scholar. In my search, I used key terms like “urban planning,” “transportation planning,” “urban history,” and “street design,” to find sources which stood out as interesting and academically prominent to me. Finding sources broadly relevant to my concentration topic was not particularly difficult, though I was unsure as to the disciplinary bents which should be represented; are we looking only at sources with an interdisciplinary focus, or would disciplinarily narrow works be welcome at this stage of concentration development? Additionally, it was difficult to find sources with the kind of situated context that is used in ENVS; while there are plenty of city-specific urban histories, the focus in that research seems to be on the place, rather than what one can learn about the topic from situating it. In some ways, the least academic and most qualitative works in this bibliography are the most suited to further situated context exploration; Jane Jacobs situates The Death and Life of Great American Cities in an incredibly detailed and personal way in the neighborhoods of New York (with some more infrequent examples from Boston and Chicago), and Allan Jacobs seems to illustrate how streets vary by context in an interesting way.
