书目末尾产生额外的数字

Question

当我编辑文档时，末尾出现了一个多余的数字。我该如何开始实际引用并删除多余的数字(1)？

.bib

@online{BLS,
            author = {Bureau of Labor Statistics Handbook, 2016-17 Edition},
            title = {Computer and Information Research Scientists},
            url = {http://www.bls.gov/ooh/computer-and-information-technology/computer-and-information-research-scientists.htm},
            month = {Dec},
            year = {2015},
            note = "[Online; accessed 22 July 2016]"
            }

您必须将\cite{}命令插入到您想要引用的位置。如果您将其插入到 '\bibliography' 之后，它将在此处包含它并导致之后出现 (1)！
