Abstract: The classical bibliometric indicators were introduced before the year 2000, whereas the modern bibliometric and scientometric indicators were introduced after 2000 (i.e., 21st century). The notable point is that all classical indicators are mainly based on simple citation counts and some normal averaging processes. The normalization of impact factor was initiated by BK Sen in CSIR-INSDOC in around 1987. The normalization process showed a new way towards the standardization of the impact factor. Whereas, the post-2k scientometric indicators or modern indicators that were all introduced in the beginning of the 21st Century, are based on other various factors apart from simple citation count. These other factors mainly include a number of publications, the relation between top-cited papers' citations and number of publications, number of shares, or views, downloads, likes, etc. The last factors developed another new metrics, i.e., altmetrics, a new metrics concept introduced in 2010. The classical indicators were mainly source-based or journal-based indicators, i.e., it evaluated the source items or the journals. But the post-2k metrics emphasized on individual articles and authors. Starting from h-index, the other related indicators, like g-index, i-10 index, e-index, a-index, and R-index et al. are author-level indicators. A glimpse of all classical and modern metrics is discussed here with relative pros and cons.
