One of the writing tasks that modern technology has greatly improved is the delivery of publisher catalogs. In the old days authors had to send a request with a large self-addressed, stamped envelope to each publisher. The publisher would have to stuff the printed catalog into the envelope provided by the author and mail it. All of this effort took time and money.
Today you can visit most publisher websites and download a PDF version of their most recent catalog. It only takes a few minutes to have a copy of the catalog in your hands. Great improvement, I’d say.
