Each publication has some requirements as to length, format, etc., just as ordinary journals do. The easiest way to make your manuscript available is to put it on your WWW page and post an announcement on mailing lists related to your topic that it is available, along with the WWW address. You can do it quickly and easily, once you know how to do it. More and more universities and institutions allow faculty and students to post WWW pages. If you spend a few hours to learn how to make WWW pages, you can make a simple page for your publications.
Interested people can read it, comment on it, etc.
This method is quick and economical. However, its disadvantage is that it is not considered to be a publication, so you cannot claim it as a publication for the purpose of promotion or job applications. When you prepare a manuscript for publication, you need to be sure to make a good manuscript. First of all, the format of your paper has to follow the format required for the publication you are submitting it to. Many journals have their own style sheets, and you need to follow them.
