While several aspects of open research software libraries have been studied, their in-code citation practices remain an unexplored area. In-code citations are citations of published scientific contributions added in the programming source code of research software libraries. In this paper, 73 such libraries are analyzed to determine the availability and consistency of in-code citations and reference sections. Findings indicate that 54 (73.9 %) of these libraries have at least one in-code citation. However, 47 had at least one incomplete citation and 89.3 % of libraries with several citations used multiple formats for citations. For reference sections, 36 of the libraries investigated in this study had at least one section. Still, inconsistencies in formats were also present as 83.3 % of the libraries with two or more sections used multiple formats for the sections, which may prevent automated programmers from indexing and collecting the list of references. Most importantly, this study investigates the availability of a systematic method that allows for the linking of references and in-code citations. Findings indicate that only six of the libraries had such a method, although many did not fully implement the method.

尽管已经研究了开放式研究软件库的多个方面，但它们的代码内引用实践仍未开发。代码内引用是在研究软件库的编程源代码中添加的已发表科学论文的引用。在本文中，对73个此类库进行了分析，以确定代码内引用和参考部分的可用性和一致性。结果表明，这些库中有54个（73.9％）至少有一个代码内引用。但是，有47篇文献至少被引用不完整，有89.3％的文库被多次引用使用多种格式进行引用。对于参考部分，本研究中研究的36个库中至少有一个部分。尽管如此，格式上的不一致之处仍为83。具有两个或多个节的库中有3％的节使用了多种格式，这可能会阻止自动化程序员对索引列表进行索引和收集。最重要的是，本研究调查了一种系统方法的可用性，该方法允许将参考文献和代码内引文链接起来。调查结果表明，只有六个库具有这种方法，尽管许多库没有完全实现该方法。
