The image contains three pie charts of a library’s expenses with five-year gaps. Over the years, there were fluctuations in the amounts spent on different types of costs, with the largest percentage shift happening in upgrades.
Initially, in 1995, renovating the library was the biggest cost, sitting at one-third of the total, and in the next five years, it rose to 43% of the total. However, this trend did not continue in the following five years, as it decreased suddenly to less than a quarter at 17%. Similarly, staff pay experienced 5% increase in the first five years, but saw a 4% decline in the next five years.
In stark contrast, purchases of both new books and technology initially fell, 5% for technology and 6% for books, then increased. Technology shot up to 27%, but books had a slower rise from 14% to 25%. This shows the library’s efforts to modernize by investing in its technology. Remarkably, miscellaneous cost did not change in trend, as it constantly declined from 7% to 4% at first, and then from 4% to 3%.
