Characterization of veterinary pharmacy and pharmacology literature and its availability to pharmacy education

Objective. To characterize the veterinary pharmacy and pharmacology literature cited by veterinary drug monographs and journal articles and describe the database indexing and availability of this literature in libraries serving pharmacy schools. Methods. Citations in American Academy of Veterinary Pharmacology and Therapeutics monographs, Journal of Veterinary Pharmacology and Therapeutics (JVPT) articles, and Plumb’s Veterinary Drug Handbook, Eighth Edition (Plumb’s) were analyzed for publication type and age. Three zones of cited journals were determined by Bradford’s Law of Scattering based on citation counts. Results. Monographs most often cited journal articles (1886 [64.7%]), unpublished “grey” literature (632 [21.7%]), and books (379 [13.0%]), but only a few cited proceedings (16 [0.5%]). In JVPT, articles predominated (9625 [91.9%]). Articles comprised 54.8% (1,959) of Plumb’s citations; pro-ceedings, 27.0%; books, 15.7%; and grey literature, 2.5%. The age of cited items varied, with 17.1% of monograph citations less than five years old, compared to 26.3% of cited items in JVPT and 40.5% of cited items in Plumb’s being less than five years old. Zone 1 consisted of three veterinary journals for monographs, four veterinary journals for Plumb’s, and 16 veterinary and human journals for JVPT. Indexing coverage was above 92% in Web of Science, Scopus, and PubMed for zone 1 and 2 journals. Libraries serving both pharmacy and veterinary education programs subscribe to 95% of zone 1 journals, while libraries serving pharmacy education at institutions without a veterinary program subscribe to an average of 59% of zone 1 journals. Conclusion. Veterinary pharmacy and pharmacology literature relies on journals from human and veterinary practice, veterinary proceedings, and, less often, books and drug manufacturer information. Libraries supporting pharmacy programs could contribute to the education of future pharmacists who will be filling veterinary prescriptions by increasing access to this literature.
