From the Lawrence Daily Journal-World for May 1, 1988:

An article today detailed some of the changes made by Lawrence postmaster Bill Reynolds since he had taken over the job 1 1/2 years earlier. Among other things, Reynolds had increased the number of post office boxes by 600, added a change machine for single-stamp purchases, installed a postage machine for sales of books of stamps, and implemented many other conveniences that had led to shorter waits in line. He had also begun keeping the post office open until 5:30 p.m., rather than the former 4:30 closing time, and for the last two years had stayed open until midnight on April 15 for income tax filers. By shifting schedules of postal carriers and bringing in mail from Kansas City earlier in the day, he had worked to meet his goal of getting every piece of mail delivered on the same day that it arrived in Lawrence. Looking at the city’s growth, Reynolds predicted two new zip codes would be added within the next six to twelve months. He also hoped to win approval by 1990 or 1991 for a new Jayhawk Station to replace the current facility at 1519 W. 23rd Street.
