Vnuk, R. (2015). Collection Development: The Basics and Beyond. https://www.youtube.com/watch?v=3IEVL8WV73o
Rebecca Vnuk is the Editor, Reference and Collection Management for Booklist. This video covers collection development basics. Some of the topics that she spoke about include organizing the budget, weeding and writing plans. Current topics of media and ebooks is also covered. The video is 1 hour and 25 minutes long, including question and answers at the end. The topics are based on her experience from public libraries.
A part that I found useful was when she went over each different professional review sources for ordering and what is good or bad about each. There are so many different resources that review materials that it can be really overwhelming and confusing. Mrs. Vnuk gives a brief overview of each, including what each publication focuses on and how they review. She also gives her opinion on them personally.
