Book excerpt: This book offers everything you need to know about selecting and implementing the best integrated library system (ILS) for your library, whether you purchase and install it yourself or hire a consultant to assist you. This is the book you've been waiting for. Integrated Library Systems: Planning, Selecting, and Implementing is an all-inclusive guide to acquiring a new ILS. Detailed and practical, the book covers every step of the process, from cost-benefit analysis, to evaluating software, writing the request for proposal, and implementation and training. You'll learn about different types of integrated library systems—standalone, turnkey, hosted, software-as-a-service (cloud computing), and open-source—and how to assess your facility and staff to find the best fit. The book also covers evaluation of software and hardware; third-party add-ons, such as RFID; and writing successful budget proposals and justification statements. There is even specific, headache-saving advice on working with sales reps, such as the warning not to ever accept the statement: "The vendor will not be held accountable to the contents of the RFP." Even if you're working with a consultant, this book will help you understand the process and make informed decisions.
