We do not know the reasons why you are searching for a full text dissertation. Perhaps, you have realized that you are not able to complete this project. Maybe, you need full text dissertations to help you with your own work. Anyway, it seems that your search for full text dissertations is not effective.
 
Actually, it means that your searching skills are somewhat poor. You do not know the effective ways of looking for something in the Web. These are the bad news for you, since:

1. You will not find a necessary full text dissertation
2. You will not find any other helpful information for your paper.

That is why let us concentrate on the main rules of searching full text dissertations in the Web.

• Have you heard of a searching bar? Every search engine is provided with a special place for entering key words.
• But wait, have you heard about key words? This is, in fact, one of the main factors of your successful search for full text dissertations. Key words should be as closely related to what you are looking for as possible. To get more precise results it is better to put the key words in quotes.

• Now, let us return to the full text dissertations. If in a searching bar you type in “full text dissertations” or “dissertation full text”, you will get thousands of useless web-sites. They will offer you papers on all the possible dissertation topics, but you will not find a necessary full text dissertation among them.
• What you need to do is to narrow down your search by more detailed and precise key words. It should be at least “biology full text dissertation” or better “stem cells full text dissertation”.

Still, we would not recommend you to pull your leg with all those search engines. You have to find several reputable dissertation databases like ProQuest or UMI, log in to their web-site and use original full text dissertations.
