Guide to the WHDL
The WHDL is not a library in the strict sense of the word. You don't check out and return books here. But HOW you access the content may differ depending on your needs.
Most libraries are run by a database, which means you can only find content if you define the variables correctly. If you search for the title of a book, and accidentally have set the search to look for authors, you will get no results. The WHDL search is more like a web search than a database search. You don't need to define any variables, because the search will look for everything in the repository that meets your criteria, just like Google. Your search results will be presented in an order based on relevance.
Also like Google, if you have too many results, you can filter your results by different categories that will appear in the sidebar.
When you see your results, you can click on the title of the resources to see more detail. For information on how to download resource files, see this article.
One of the goals of the WHDL is to help people know that certain types of resources even exist. In many countries, this is a big need. Therefore, for some titles where we do not have permission to post the full resource for free, we have listed a link to where it can be purchased. For other titles, even though the digital resource is free, there exist hard copies that can also be purchased. In these cases we have given you not only the digital file, but a link to where you can purchase a hard copy.
Lastly, we have made an effort to list the various copyright restrictions pertinent to each resource. Public domain files have no restrictions. Some files, given freely through the WHDL, are under the ownership of specific parties. In these cases the copyright tab will indicate that the resource is free for personal use only. It is not legal to create products for sale from those particular resources, or to make multiple copies and distribute them without permission from the WHDL.
