What are the different searches?
The main search (Wide Book Search) has four choices:
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 books or electronic documents containing your keyword.
Directories: This search will find directories with what you may be looking for.
Document Titles: This search will find documents with your keyword for their title.
URLs: This search will find a URL with your keyword in it.
Text: This search will find documents with your keyword in the text - good for finding a passage.
The second tab will find files by document type (Search by Document Type).
Most ebooks appear in pdf (Acrobat) or chm 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. Many books also appear in txt format - especially books for school age children.
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 books that this search engine finds?
Unfortunately, no. We have left it up to user discretion and knowledge. Different countries have different copyright regulations, and so while a particular book may be in the public domain in one country, say Australila - you can find it with our search engines in the UK, where it may still not be in the public domain.
This search engine also finds a large number of hidden caches of books that people have stored on their servers illegally. Please support the hard work of these authors and buy the real copy if you like the book or support them in some way.
Are there other ways to find books online?
Yes. You can try using BitTorrent. There is also a "Torrent" finder plugin for Firefox that will also search for torrents of books. Then you need a "Bit Torrent" application to downoad the "torrent".
Is there a way to see if the book I want is at my local library?
Actually, there is. A gentleman by the name of Jon Udell created project that does just that. He calls it the "Library Lookup Project". Follow my link to read more about it.
