Best Bets used to be single-week-loan no-holds books at certain branches. The policy was changed – I could link you to the PDF, but why bother – and now they are simply no-holds books with three-week renewable loan periods.
Essentially, then, every Best Bets collection – I count 38 open today – is now a mini-Browsery, as the treatment of such materials is indistinguishable from those in the two extant Browseries. And as such they render those two Browseries’ books obsolete, though this news has not quite reached TRL.
Update (the next day): Without even having to ask the question, somebody at the desk at TRL told me the loan period of its Best Bets autoflipped to three weeks on July 1. So it’s just a question of ugly homegrown signage and covering up stickers with other stickers.
