The ever expanding usage of mobile technologies has dramatically changed how we access information and how we as a society expect to access information. With mobile technologies becoming available to an increasing majority of the population, users are constantly connected to information. The rapid expansion of mobile technology has had a profound impact on many different sectors, industries, and institutions, among those that have been affected are libraries. With more users expecting access to information and resources in a mobile optimized format, libraries have had to adapt to meet the needs of users. This has entailed evaluating various library services and resources to determine how to best meet the needs of mobile users. Additionally, mobile technology has changed the way that websites are designed, and has led to an increasing popular type of web design know as responsive web design (RWD). This enables web developers to design websites with one code base that are optimized for a wide range of devices from desktop computers to smartphones. Libraries must keep their mobile services current or risk becoming obsolete. Based on research, examples, and experience using mobile technology, this book will include topics such as: -The impact of mobile technology -Mobile technology and the Digital Divide -Implications for library staff and vendors -Responsive Web Design -Wearable technology in library services Mobile Technologies in Libraries: A LITA Guide is written for library staff interested in how mobile technologies have changed the way we access, and expect to access, information, as well as how libraries can incorporate and adapt to mobile technology.
