A maturity model represents a pre-planned evolution path for a class of objects composed as discrete stages or levels. Thereby, the maturity model is an effective tool to assess the current capabilities and the future needs of an organization, process, or group. This study had two phases. The first phase identified the core literature on maturity models for library services and management. The second evaluated the specifications of the maturity models employed or derived for library services and management. A total of 12 maturity models were selected for the study. The selected models were reviewed based on 18 parameters, out of which nine were adopted from the literature study, and the authors identified nine others. These parameters were classified based on descriptive, structural, and administrative attributes of the models. The parameters help to identify the most appropriate maturity model for implementing it in a library or information center. Results show that several domain-specific free and commercial maturity models can improve the library and information services. Library and information professionals should utilize the opportunity available in user training and community support for maturity models to foster information services.

成熟度模型表示由离散阶段或级别组成的一类对象的预先计划的演化路径。因此，成熟度模型是评估组织，流程或小组的当前能力和未来需求的有效工具。这项研究分为两个阶段。第一阶段确定了关于图书馆服务和管理成熟度模型的核心文献。第二部分评估了为图书馆服务和管理采用或推导的成熟度模型的规范。总共选择了12个成熟度模型进行研究。选择的模型基于18个参数进行了审查，文献研究中采用了9个参数，作者确定了其他9个参数。这些参数是基于模型的描述性，结构性和管理性属性进行分类的。这些参数有助于识别最合适的成熟度模型，以在图书馆或信息中心内实施该模型。结果表明，几种针对特定领域的免费和商业成熟度模型可以改善图书馆和信息服务。图书馆和信息专业人员应该利用用户培训和社区支持中的机会来成熟度模型，以促进信息服务。
