It provides an overview of the potential benefits and challenges, including strings that may be attached to donations and possible influence on the library's mission. It also addresses the need for libraries to have clear donation and naming policies to guide these relationships transparently and avoid prioritizing private interests over library users and values. A survey found most libraries have not faced ethical dilemmas but some noted issues like patron complaints or disallowed self-published donor materials. The document concludes by offering tips for libraries to cultivate corporate donors while protecting their reputation and independence.
