This document summarizes a presentation about e-books in public libraries in the US and Poland. It shows that while e-book usage is higher in the US, at 20% compared to an unknown percentage in Poland, e-book lending is becoming more popular in public libraries. The presentation discusses the largest e-book vendors in the US - Overdrive, NetLibrary/EBSCO, and Ingram - and capabilities they provide like large digital collections, compatibility with devices, and integration with library systems. Finally, it outlines options for Polish libraries to acquire e-books, such as purchasing directly from publishers or using retail or vendor platform solutions.
