I used to spend weekend afternoons at the library researching and reading. Nowadays I use the Internet, though I still take biweekly trips to the library with my son to check out books (literally and figuratively).
If I wanted to buy a rare title, I used to contact a local bookstore and have them do a search; a week or two later I would hear if they had found one and, if so, begin the process of ordering it. Nowadays I type the title into Bookfinder, order the copy I want, and a week or two later it arrives in my mailbox!
I used to write letters to my grandparents and uncle in England; about a month later I would receive their reply. Nowadays I attach a few pictures to an email, press ‘send,” and within minutes I have a reply!
I used to post flyers at bookstores and cafes seeking people to start a critique group. Nowadays my local SCBWI has a gal whose sole function is to match people to groups (via email, of course!).
I used to type stories on an old manual typewriter with sticky keys. Then, in college, I bought a fancy electric typewriter. After college I bought a bulky “word processor” that weighed about 20 pounds. A few years later, I bought a smaller version of the same word processor. About 15 years ago, I bought a Compaq Presario, an “entry level” computer. Since then I have written on various cheaper and faster versions of desktop or laptop computers.
I used to seek out books and seminars on writing. Nowadays I read websites and blogs, and even post to our own blog!
I used to package submissions in a manila envelope with a SASE, send it off, and wait a few months (or more) for a reply. Nowadays – hold on a second: that’s what I still do!
