Although the need of proofreading services is getting smaller and smaller with the advance of software technology, there are still companies that offer authors and publishers to do this work. The idea of proofreading is to correct any mistakes made by typing machines or human spelling, and also any other grammar mistakes. This is the last correction that the art work will get before being published. That’s why it is very crucial that this service is done correctly.
Different companies provide different professional proofreading services. Some of them do the traditional tests, in which a reader reads thoroughly the whole text and correct any mistakes. They use special proofreading software which helps them do their job more accurately. They do not correct the mistakes themselves, but only mark the text where necessary.
A cheaper alternative of the traditional proofreading service is the so called scanning. In this case the text is not read thoroughly, but quite quickly and vaguely, but clearly enough to detect any errors. This method is gaining more and more popularity with the advance of software technologies and their broader functions. On the other hand the price of these proofreading services is much smaller rather than the traditional ways. The disadvantage of this method is that the level of security is not very high.
Another type of proofreading services is the multiple check. In this method one of the readers read the text out loud and without stopping to correct any mistakes. The second reader follows the text and marks the errors. In this way at the same time are checked both the grammar and the spelling mistakes for a much shorter period.
As pointed correctly at http://www.a-mentor.co.uk/services/proofreading-service/ the double check is another method for proofreading service. In this way the text is read first by one reader who corrects all the mistakes. After he is finished with that he passes the text to a second reader, who checks the whole text again. In this method both readers need to put their signatures under the given text and after that they take responsibility equally.
Many people think that it is not necessary for a person to have a special proofreading education before that. Many critics say that it is actually more important for the readers to have knowledge on the matter that they are reading, because thus they will be able to check the text more accurately, covering not only the common words, but also the specific ones too.
