Purpose

This study aims to investigate the facilitating conditions (FCs) and how these FC affect institutional repository (IR) sustainability practices in public universities in Nigeria.

Design/methodology/approach

A survey research design was adopted in this study. The study population comprised 542 librarians from public universities that have IRs across Nigeria. A sample size of 230 librarians was determined using Taro Yamane’s formula. A multi-stage sampling technique was used to select the respondents in three stages, which were purposive, stratified and purposive sampling. A structured, validated questionnaire was used for data collection. Data were analyzed using descriptive and inferential (simple and multiple regression) statistics at a 5% level of significance.

Findings

The result revealed that the availability of FCs (ßeta = 0.459, t(211) = 7.719, p = 0.000) has a positive and significant influence on IR sustainability in public university libraries in Nigeria. The F-test (1, 223) value of 59.582 shows that there is sufficient evidence to substantiate the model’s usefulness in explaining IR sustainability. The R² (0.211) indicates that 21.1% of the variation in IR sustainability is explained by the availability of FCs in public university libraries in Nigeria. The finding suggests that the availability of FCs is a vital predictor of IR sustainability in public university libraries in Nigeria. The result also depicts that out of the eight parameters that measure the availability of FCs, it was current awareness of IR that had a positive and significant influence on IR sustainability.

Originality/value

This study concluded that ICT skills and FCs are contributory factors to IR sustainability practices by librarians in public university libraries in Nigeria. It was recommended that university administrators formulate policies that promote the sustainability of IR and provide adequate funds to support IR sustainability. Furthermore, the library management in public university libraries in Nigeria should drive content recruitment and create awareness of the IRs among students and faculty to ensure continued use.

尼日利亚公立大学图书馆的图书馆员促进条件和机构存储库的可持续性

目的

本研究旨在调查促进条件 (FC) 以及这些 FC 如何影响尼日利亚公立大学的机构存储库 (IR) 可持续性实践。

设计/方法论/途径

本研究采用了调查研究设计。研究对象包括来自尼日利亚各地设有 IR 的公立大学的 542 名图书馆员。使用 Taro Yamane 的公式确定了 230 名图书馆员的样本量。采用多阶段抽样技术，分三个阶段选择受访者，即立意抽样、分层抽样和立意抽样。使用结构化、经过验证的调查问卷来收集数据。使用描述性和推论性（简单和多元回归）统计数据以 5% 的显着性水平对数据进行分析。

发现

结果表明，FC 的可用性（ßeta = 0.459，t (211) = 7.719，p = 0.000）对尼日利亚公立大学图书馆的 IR 可持续性具有积极且显着的影响。 F检验 (1, 223) 值为 59.582，表明有足够的证据证实该模型在解释 IR 可持续性方面的有用性。 R 2 ( ^0.211 ) 表明 IR 可持续性变化的 21.1% 是由尼日利亚公立大学图书馆 FC 的可用性解释的。研究结果表明，FC 的可用性是尼日利亚公立大学图书馆 IR 可持续性的重要预测因素。结果还表明，在衡量 FC 可用性的八个参数中，当前的 IR 意识对 IR 可持续性产生了积极且重大的影响。

原创性/价值

本研究得出的结论是，ICT 技能和 FC 是尼日利亚公立大学图书馆图书馆员 IR 可持续实践的促成因素。建议大学管理者制定促进IR可持续性的政策，并提供充足的资金来支持IR的可持续性。此外，尼日利亚公立大学图书馆的图书馆管理人员应推动内容招募并提高学生和教师对 IR 的认识，以确保持续使用。
