Libraries have long been involved in content management due to their mission and task, but with the advent of the digital age, this content has changed from print to digital. Digital content management is related to storing, organizing, indexing and monitoring digital content used by an organization. Digital content can take many forms, including text files, documents, graphics, images, animations, and audio and video files. This book is a handbook consisting of 15 chapters in the field of research on digital content management and development in libraries, elaborating on various areas such as: Consortia, Digital Libraries, Digital Resource Management, EResources, Information Retrieval, Knowledge Management, Open Access, Repositories, RFID Technology. Even so, in this book, the research topics mentioned have not been studied in depth. In my opinion, considering the thematic importance of the book, it would be better to address newer research topics such as cloud computing, artificial intelligence, digital twins, virtual reality, research data management, etc. It is suggested that a new collection consisting of the chapters of the proposed areas be compiled.
