What is a Full Text Database?
A full text database is a database that is presented in online form. It is possible to search for specific terms, keywords, subjects, and dates. The difference between a full text database and a regular database is that the full text database has the option of viewing the texts in full form, right there online or somewhere else in the database. The most common use for these databases in on school and college campuses, but there are also full text databases for other things. The full text database for U.S. patent information is very useful.

History
-
Full text databases started to emerge around the 1950s and 60s. The first instances of full text databases were entered on microfiche imaging systems. They were hard to use, and data was easily lost. However, with the creation of the Internet, and other online networks, it became possible to store images of documents much easier and safer. This led to the current format of most full text databases.
Function
-
The purpose of full text databases is so that information can be easily accessible to students and other who may need to view the information while the libraries are closed. This option is very useful to people who are conducting long term studies and for professional researchers. Many colleges and other libraries use these full text databases to preserve their materials and to save space.

Features

Most full text databases allow for searches in several different ways. Usually it is possible to search by subject, keyword, date, author, or title. The results can be displayed in several formats. Usually there is the option to view the data by .txt format, word document format, PDF format, or HTML format. Multiple viewing options allow more people to view the information. Usually membership to these databases comes with admission to colleges and universities. However, it is also possible to pay a membership fee to gain access to databases that would not otherwise let someone access them. This allows someone to complete more extensive research without travel.
Benefits
-
There are many wonderful benefits to full text databases. One of the main benefits is the ability to preserve old texts and re-publish their information. Another great benefit is the benefit of saved space. Libraries do not have to be as big now, which enables them to hold even more information in a small space. A benefit to researches is the ability to study information any time of the day. With the right subscriptions, it is also possible to study materials that the person otherwise would not have access to.
Size
-
The size of full text databases varies between the owners. Most institutions such as colleges and libraries have at least a small full text database. Most of the materials available for viewing in full text database form are old periodicals and newspapers. Some places have a large selection of information, while others have a smaller selection. However, it is likely that full text databases will only grow larger in number and more extensive in information in the future.
