作者：
Highlights：
• The total number of citations is growing annually by 5.6% and doubling every 12 years.
• The growth of science impacts fundamental properties of the science citation network.
• Both very recent and very old literature are being cited less and less.
• We developed & tested a generative citation network model.
• We simulate and analyze the impact of shifts in citing behavior on the citation network.
