Computer/Internet Books (Reading)

2020k (Computers&Internet) large collection nicely sub-categorized links to downloads in varying formats.  Note:  Most of the links here are working, but there are a number that lead to BookRags, which are not free anymore.  Unfortunately, there is no way of telling where the link goes until you click the link.  Since they did fix the issue with archive.org links, hopefully they will fix this.

January 25, 2014, 30 new sites added, 2 links fixed. All links here checked and working. There are now 119 sites listed here.

I use LinkChecker to check page links and no longer visit each site individually to reconfirm. So, if you find a site that is not as it should be, then please post here in the comments.

If you know of a site to be added to this listing, please post here in the comments.

If you are the owner of a site that you would like added to this listing, it is better to contact me through the site (click on mr6n8).

Also, no site that has an orange or red rating from WOT (Web of Trust) may be added to this listing, per site rules. So please check the WOT rating before posting.

Thanks

I tried the bestbooks link for an Access book,
got some pop-ups (apparently I'm a winner) and ended up at icefile.org, still no sign of the book, more pop-ups, gave up, be easier to write my own book.

by mr6n8 on 27. April 2011 - 13:24  (71011)

Thanks. I have removed.

The downloads were working properly when I first added the site, but it looks like it has turned into a spam site.

I tried one and got icefile and on another I got an office supply site.

Thanks again. Your input helps to keep the list clean.

Steve

Edit: After re-checking the site, it appears that one of the sites they link to has become a spam site. Many of their links still work. In fact, several of the links to books on Access are legitimate. I have written the site to remove the spam site links and if they do I will add them back in.
