Reading with a card or something can help but isn’t it difficult when you have to proofread an article on your computer or laptop? I think it is. In fact, for me it is impossible. So, I am using other techniques to make sure that what I write (other the comments) is typo free.
1. I use Google Dictionary, that I have embedded in my browser, to check the accuracy of each and every word by double clicking on it. When you would do so, and if you would, a pop-up window will show the meaning of the word you have written.
2. To check names of individuals, places and companies I use Ctrl+F function. With this, you can actually search and replace all the names in your document, just before hitting publish or submit.
Two other techniques I use are to:
1. Read my work backwards from bottom to top – even scan from right to left. This helps prevent the familiarity issues that cause authors to repeatedly miss – missing words, repetitive words and phonic errors – “their” for “there” as appropriate.
2. Just keep writing so that there are several days if not weeks between writing and proofing. Again this limits the authors familiarity with the work from continuing to read over obvious problems. Go back an read your old second rough drafts and see how easy it is to spot the errors you missed on your first editing draft when it was all fresh.
