Volunteers pitch in at Concord bookstore as owner recovers from surgery

For most of the past 15 years, Concord’s Berkshire Books has been a one-man operation, with Lynn Kuehl buying, selling, stacking, shelving and otherwise handling the books and doing the chores common to an independent bookstore.

That changed on Nov. 14, when the 65-year-old Kuehl was starting his day, getting ready to go to his Clayton Road store when he noticed he had no feeling in his right foot. Doctors told him he had had an aneurysm in his right knee, cutting off circulation. It couldn’t be fixed, and he lost his leg soon after.
