The one I use is Luzme It queries several stores including Kobo, Amazon, B&N and in several countries.
It then for each book shows the price that it last saw for each source and country.
It is searchable by book name and author and series, although the series data is not complete as it comes from the stores.
You can set up a wishlist of books and ...
Calibre is a downloadable (free, donations accepted) application that will allow you to search over multiple stores, for content. Using the get books function, to provide information like comparative pricing between retailers and DRM status of the work at different retailers.
Yes there are. The one I remember is Inkmesh.
You can filter by price, type (ebook, magazine, audiobook, etc.) device and language. Its database has large gaps though.
This site does not provide DRM status.
The short answer is that any website offering permanent access to large numbers of copyrighted books, for very little money, from multiple publishers is unlikely to be legitimate.
HumbleBundle offers its bundles for limited time.
Book Barbarian, ManyBooks, BookBub, Luzme, and no doubt many others, search the web on your behalf and find books that are ...
Amazon only enhanced search engines (I'll group these together since they don't quite fit the question, but are still worth a mention).
Jungle-Search is an interesting search engine. It's not limited to ebooks and is Amazon only (though you can choose from various Amazon stores, such as CAN/US/UK/GER/FRA). The purpose of this search engine is to allow you ...
There is a decent search engine called Leatherbound ebook search engine. Like Inkmesh and Luzme it allows you to search for a book across multiple stores and price compare. Here is a sample search result (for an entertaining book I might add).
In addition, you can search for printed books, free ebooks, ebook under $5 and some advanced search options.
You can use the GrabMyBooks Firefox extension. It can grab single web-pages and convert them to epub, or adding multiple pages as distinct chapters.
There is also a Calibre plugin called FanFictionDownloader, but I've never used it.
I don't necessarily endorse using it for all your reading, but there are some fine subreddits to suggest book titles. https://www.reddit.com/r/suggestmeabook/ . Also check out the booklists subreddit. Also, fivebooks.com is creating a whole universe of book suggestions by subject area (though more for academic topics). Finally, I agree with what you are ...
Your question is really too broad and unprecise to respect the usual
rules of Stack-Exchange. However, I will try to answer it in a way
consistent with such rules.
There are many places where books are discussed, but they are usually
specialized in some way. And no one is going to list the
possibilities, not here.
My best advice is for you to search the ...
SIGIL is probably not your best tool for creating static HTML files although it's not impossible.
The main goal of sigil is to produce an epub file, and to read an epub in the browser, you'd need to install a special extension (Readium).
If you get down to it, epubs solve a navigation problem -- of flipping between chapters and of creating a TOC.
