Literature of Acquisitions in Review, 2012–13
The acquisitions literature published in 2012�13 shows a strong focus on nontraditional purchasing models, especially for electronic books (e-books). Patron Driven Acquisition (PDA) is one method that helps librarians cope with budget constraints that continue to plague library budgets. The expense of Big Deals has some libraries seeking more efficient alternatives such as Pay-Per-View or Evidence-Based Selection, however, many libraries are still reliant on the depth of coverage and perceived value of Big Deals. This review will cover these trends along with developments in Electronic Resources Management Systems (ERMSs), workflow efficiencies, and negotiation and licensing techniques.
Comparative study of the molecular species of chloropropanediol diesters and triacylglycerols in milk fat
In an effort to establish the origin of the fatty acid esters of 3-chloropropanediol, which recently have been isolated in small amounts from goat milk, we compared the molecular species composition of the chlorohydrin diesters and of goat milk triacylglycerols. The chloropropanediol diesters were found to be composed of molecular species containing C10−C18 fatty acids and corresponded closely in carbon number to those calculated for the long chain sn-1,2-diacyl-glycerol moieties of goat milk triacylglycerols. The molecular species of goat milk total triacylglycerols contained C4−C18 fatty acids. It is suggested that triacylglycerols and chloropropanediol diesters are derived from the same pool of long chain fatty acids. A molecular distillate of bovine milk fat did not contain chloropropanediol diesters, while the available samples of human milk fat were shown to contain alkyldiacylglycerols as the major components of a neutral lipid fraction corresponding in polarity to the chloropropanediol diesters.
