But there remains a perceived finality to the deselection decision. That perception is in many respects false, as it is perhaps easier to re-obtain content now than at any time in history. Irreversible mistakes are rare. But the stakes seem high, and for now it is rare indeed to meet a selector who will withdraw a book without looking at it. In the previous post, we considered deselection from lists. Here we look at the costs associated with book-in-hand review. There are two approaches, each with slightly different time investments: in-stack review and staged review. Today we consider the first of these:

1. Marking the Candidates: Again, let's assume that a student worker, using a list arranged in shelflist order, can find an label 1 title per minute. This may seem slow, but this average has to incorporate looking for items that are missing or misplaced, annotating the list, and moving or marking found items. In eight hours, 480 books could be marked. Let's round up to 500/day.
To mark our entire list of 10,000 withdrawal candidates, then, would require 20 person-days at 500/day. If we assume an 8-hour day and apply a student wage of $10/hour, the process of finding and marking the withdrawal candidates is about $1,600.
Let's assume these thought processes and actions take twice as long as the marking; i.e., allocate an average of about 2 minutes per title. That equates to 250/day. Our 10,000 titles would require a total of 40 person-days. If we assume an 8-hour day at $35/hour, the cost of in-stack review by deselectors is approximately $11,200. ($280/person-day x 40 days).
The total cost for in-stack review:
- $1,600 for marking
- $11,200 for deselection decisions
- $12,800 Total, or
- $1.28 per title
