Frequently Asked Questions

What are the different searches?

Each search has four choices:

  • PDF (Adobe Acrobat files)
  • CHM Files (Compiled HTML - eBooks)
  • Microsoft Word Documents
  • RTF (Rich Text Files)
  • TXT (Plain unformatted text files)

These four searches look for documents with your keywords in them and add them to our Boolean string designed to extract the highest number of documents of the chosen type, containing your keyword.

Many online ebooks can be found in pdf (Acrobat) or chm (Compiled HTML) format. Sometimes it is enough to look for a document in the .pdf format to find exactly what you are looking for. You almost always find something interesting. If you do not have luck finding what you are searching for in your chosen format, try TXT files as a last resort - you will probably find something reasonably close if not an exact match.

What is a PDF file?

PDF stands for "Portable Document Format, and is a standard created by Adobe for the exchange of professional documents.

A PDF file encapsulates a complete description of a two-dimensional document (and, with Acrobat 3D, embedded 3D documents) that includes text, fonts, images, and vector graphics.

Formerly a proprietary format, PDF was officially released as an open standard on July 1, 2008. Anyone may now make a reader or utility for the PDF format.

How Do I read a CHM file? How can I open it?

This is much simpler than you thought and much simpler than it used to be. You need to have the Firefox browser installed, and then simply get the CHM Reader plugin. If you are not now using Firefox, you should give it a try, it is free and it has many useful plugins, such as the one for reading CHM electronic books.


Is it legal to download all the documents that this search engine finds?

Unfortunately, no.

You should know that. Everything you find on the Internet is not necessarily legal, so use caution when downloading files.

We have left it up to your discretion and knowledge.



Different countries have different copyright regulations, and so while a particular document may be in the public domain in one country, say the UK - you can find it with our search engines in the the United States, where it may still not be in the public domain.

This search engine also finds a large number of hidden caches of documentss that people have stored on their servers illegally. If you find such an illegal cache of books or e-documents, please support the hard work of these authors and buy the real copy if you like the book or support them in some way.
