In the 2017 fiscal year, participating institutions acquired a total of 178,120 books. Of these, approximately 96 percent were acquired as tangible print books and the remaining four percent as electronic books (see Figure 1).
Figure 1. Percentage of Print vs. Electronic Books
Print books were overwhelmingly acquired through a firm, one-time purchase, with 95 percent obtained in this manner. Only a little more than three percent of books were acquired through an approval plan, and half of that number were through a standing order. Electronic books, however, were acquired in drastically different ways. Firm purchases of ebooks fell to a little less than 60 percent, while approvals rose to 11 percent. Ebooks acquired through “unknown” means shot up to 31 percent (see Figure 2 and Figure 3). Although we do not know what these unknown acquisition methods are, one thing to note is that integrated library systems often have no systematic way of capturing items obtained as demand-driven acquisitions (DDA). It is therefore possible that these unknown acquisition methods include DDA. These preliminary findings are unexpected and represent an area that we would like to delve into with greater detail in the next stages of the analysis. Are these findings consistent with other library’s buying practices?

Figure 3. Percentage of Electronic Books by Acquisition Method
The median price of electronic and print books by their acquisition method also varies to a wide extent (see Figure 4). Print books were acquired for a substantially lower median cost than electronic books, especially for print books and ebooks obtained through standing orders. While these figures suggest that electronic books generally tend to have their prices set at substantially higher rates, this could also mean that the specific books that institutions choose to acquire in electronic format simply cost more to obtain.

Institutional Type Differences
We also examined the number of book acquisitions by institutional characteristics. When examined in relation to their sector, we found that public institutions at the masters and doctoral level acquire a substantially higher number of books on average (see Figure 5). However, because we only have data for private baccalaureate schools, we were unable to assess whether this trend applies to public baccalaureate schools as well. Furthermore, because each category contains a relatively small number of schools, these findings should not be considered representative of acquisition patterns at institutions on the whole. We hope that further data gathering, especially from Alma participants, will bring greater balance to our participants in terms of institutional types.

Among vendors, GOBI Library Solutions (formerly YBP) encompasses nearly half the market share of book acquisitions made in FY2017 by libraries in our sample, while Amazon has become the second largest book distributor with a quarter of the market (see Figure 6). Other top vendors have no more than six percent of the overall market. Participating institutions spent $9,407,190 on books during the 2017 fiscal year, with median prices among the top ten vendors ranging from close to $18 to just under $35 (see Figure 7).

By discipline, GOBI and Amazon remain the top vendors across books in the humanities, social sciences, STEM, and other disciplines, although GOBI’s market share increases to 56 percent within the social sciences, while Amazon holds nearly 34 percent of the STEM market (see Figure 8). However, we question how much of these vendors’ market share is driven by the libraries themselves and their decisions to obtain books in different disciplines from particular vendors. As our research continues, and as we incorporate acquisitions data from significantly more schools, we will be interested to see whether these vendors remain the largest distributors. Amazon’s substantial presence is extremely notable among the libraries in our sample as well, and we look forward to seeing whether it has an equally substantial presence among Alma participants in the next phase of work on this project.

Conclusion and Next Steps
Our findings indicate that print books dominated book acquisitions in 2017 at the 54 participating institutions in our data set. Most of these were acquired through a firm purchase in contrast to ebooks, of which nearly half were acquired through other methods and at significantly higher prices. The average number of book acquisitions was substantially higher among public universities as well. Amazon has come to capture 25 percent of the market, making it the second largest book vendor for these institutions. By discipline, titles focused on the humanities made up roughly half of all book acquisitions in the last fiscal year.
These findings provide a snapshot of library acquisition patterns among universities that utilize OCLC’s WorldShare Management Services. While the findings in this preliminary report should not be viewed as representative of the acquisition patterns present in all academic libraries, they nevertheless yield important insights into current practices employed in acquiring books and illuminate which areas may be of most interest to dive into for a deeper analysis. The next step will be to incorporate acquisitions data from as many Ex Libris Alma participants as possible. Because we expect to add many larger research universities to our sample, it should give us the opportunity to examine patterns more broadly and at institutions with larger and potentially more diverse acquisitions. This amount of data and the greater number of schools will also allow us to take a closer look at the different patterns that may exist within different sectors of the academy and over time.
Throughout the summer we will continue to gather data to ensure a large number of acquisition records from a diverse group of institutions. The next stage of this analysis will see us answering questions that include but are not limited to:
- How many books are academic libraries acquiring on average per year, and is there any notable trend in the number of acquisitions?
- In which formats and through which methods are academic libraries acquiring books? Have these patterns seen any change from 2013 to 2017?
- How do acquisition patterns vary by institution type and sector and how are these patterns changing over time?
- From which publishers are libraries acquiring books and through which vendors?
We will present our findings in a final report in fall 2018.

 We would like to express our gratitude to the participants for agreeing to supply us with their acquisitions data, and especially OCLC’s Jonathan Blackburn for extracting it.
 The study included 46 private institutions (27 at the baccalaureate level, 17 at the masters level, two at the doctoral level) and eight public institutions (five masters level, three doctoral level).
