The Getty Museum's collection of drawings was begun in 1981 with the purchase of a Rembrandt nude and has since become an important repository of European works from the fifteenth through the nineteenth century. As in the first volume devoted to the collection (published in 1988 in English and Italian editions), the text is here organized first by national school, then alphabetically by artist, with individual works arranged chronologically. For each drawing, the authors provide a discussion of the work's style, dating, iconography, and relationship to other works, as well as provenance and a complete bibliography.

Several people have asked what motivated us to write a book about commut ing, something that we all do but over which we have very little control. As a matter of fact, the general reaction from professional colleagues and friends alike was first a sort of knowing smile followed by some story. Everyone has a story about a personal commuting experience. Whether it was a problem with a delayed bus, a late arrival, broken-down automobiles, hot trains or subways, during the past year we have heard it all. Many of these stories must be apocryphal because, if they were all true, it is amazing that anyone ever arrived at work on time, at home, or at some other destination. The interest for us likely stems from many factors that over the years have probably influenced our thinking. All of the authors studied and/or grew up in the New York City metropolitan area. For illustration, let's devote a few paragraphs to describing some of the senior author's (Koslowsky's) life experiences. As a young man in New York City, he was a constant user of the New York City subway system. The whole network was and still is quite impressive. For a relatively small sum, one can spend the whole day and night in an underground world (growing up in New York often makes one think that the whole world is contained in its five boroughs).

The widespread adoption of smartphones, ridesharing and carsharing have disrupted the transport sector. In cities around the world, new mobility services are both welcomed and challenged by regulators and incumbent operators. Mobility as a Service (MaaS), an ecosystem designed to deliver collaborative and connected mobility services in a society increasingly embracing a sharing culture, is at the center of this disruption. Understanding Mobility as a Service (MaaS): Past, Present and Future examines such topics as: How likely MaaS will be implemented in one digital platform app Whether MaaS will look the same in all countries The role multi-modal contract brokers play Mobility regulations and pricing models MaaS trials, their impacts and consequences Written by the leading thinkers in the field for researchers, practitioners, and policy makers, Understanding Mobility as a Service (MaaS): Past, Present and Future serves as a single source on all the current and evolving developments, debates, and challenges. Includes case studies to show how MaaS is delivered around the world Covers foundational aspects of MaaS, clarifying what it is for those new to the concept Offers an in-depth analysis on a wide range of MaaS topics including governance, contracts, consumer and supplier preferences, links to societal objectives, the role of trials, assessments, and more
