How to best measure journal performance remains a controversial issue. Routinely, the impact factor of the journal is taken, although this measure was never designed to reflect journal performance. The impact factor was developed as a tool for librarians in academia to sort out, which of the many very different journals may best suit the demands of their readers. As the annual impact factors are released in the middle of the year, we cannot yet share this value with you. However, our estimates indicate a similarly high impact factor as for the most recent years.

如何最好地衡量期刊绩效仍然是一个有争议的问题。通常，采用期刊的影响因子，尽管此措施从未旨在反映期刊的绩效。影响因子被开发为学术界图书馆员进行分类的工具，在许多完全不同的期刊中，哪一种最适合读者的需求。由于年度影响因子会在年中发布，因此我们无法与您分享这一价值。但是，我们的估计表明影响因子与最近几年相似。
