In line with previous reports, the Bookseller reports — based on an ad submitted to the publication — that UK wholesaler Bertrams (and its subsidiaries Dawson Books and Education Umbrella) has been put up for sale. It’s being offered by Middleton Barton Valuation (MBV), a restructuring firm. Earlier in the month, the Sunday Times had reported that parent company Aurelius was preparing to appoint bankruptcy administrators for the wholesaler.
