有前例的

Against this background, an obvious solution to the libraries' dependence on OCLC's central repository of bibliographic information is to start up an open equivalent along the lines of Freedb and MusicBrainz: basic hosting costs are now small, and altruists willing to run mirrors would doubtless start popping up given that the benefit to the community as a whole is so great.

在这种模式下，图书馆对 OCLC WorldCat 这种集中式联合目录的依赖问题，在 Freedb 和 MusicBrainz 的前例下，即有个明显的解决方案。现在基本的网路主机架站成本已相当低廉，乐意协助帮忙网站做映射处理的利他主义者，无疑地会争先加入提供资源的行列，如此能让社群整体的获益达到非常大。
