I was wondering if there is a database mod. I want something that I can upload some files or pages to and the users can pull up according to what they are looking for. Lets say they want to loose weight. They can look up routines for cardio. Or if they want to know how to do bodybuilding they can find routines for that. Or it can pull up things for the diet.

Plus I have some books I would like to post on my site to. Let the users be able to view then if they like to

There are different ways to accomplish it, but it depends what you want.

For example, do you want them to be able to download it and read later, or do you want them to be able to only read online, but not download?

For the first, you can use a module like TDMDownloads or WF-Downloads.

For reading only, if the pages are scanned, then you probably would have to convert them to a PDF document, and then you could use something like turn.js.

Wishcraft started to work on a module using turn.js, but I don't think, he ever finished that, so I don't think, it will work, but you can check it out here. Just click on the "Download Snapshot" in the right upper corner.

I would like for them to have the option. They can download or just read.
