Dear Sir,You have expressed your frustration and irritation with the city library over the past one year.There are usually long lines waiting for assistance and for use of the computer card catalogue.To avoid crowded conditions, we propose that you use the library during off-peak hours.You should have no trouble getting help and using the card catalogue during the following periods: 11:30 am to 2:30 pm; 5:30 pm to 7:30 pm.The rest are our busiest times.We always appreciate hearing your comments on the library.Please let us know how you think this is working out.Yours faithfully, Li Ming
