Unique to this archive, each story can be rated collectively!
Most fiction websites allow users to 'upvote' or 'like' fictions, even fewer allow 'dislike.'
Why not try something new?
Part of the starring system is that each vote is tallied and averaged to give a composite rating - the more people that like the fiction, the more stable the rating!
This is a bit of a new concept, so we will have to see where it goes.

FiMFiction only allows defining three different content ratings: Everyone, Teen, and Mature.
At first, this seemed 'good enough' to me, but as I recall the various fics I've read, I realized that there is a significant gap that is missing.
For instance, Fallout:Equestria is most certainly not in the same category as porn, and you shouldn't have to see porn to find others like it.
Therefore, even though I keep the ratings to match FiMFiction's archived away, I have introduced three additional rating tags to bridge the gap. (Plus one automatic rating tag to assist)
Without further ado, here are my adjusted ratings defined:

Everyone

No Swearing, Sexual references, Cartoon Violence.

Teen

Light swears ok, but nothing explict, Light sexual references, Some Blood Allowed.

Young Adult

Bad swearwords allowed, intimate non-clop allowed, May have Graphic Violence.

Adult

Fiction with explicit/mature references or an actual story with cloppy content.

Clop

Explicit Clop. The only purpose or goal of the fiction is porn.

Mature

FiMFiction Default tag.
*Fics marked 'Mature' simply haven't been re-categorized.

Dubious

This is an automatic flag: If a fiction was not rated mature, but contains 'bad' words.
(Roughly Equivalent to 'Young Adult', but not reviewed)

Many fics are going to be recategorized from 'Teen' to 'Young Adult' simply because of a 'very bad word' or two, but others because of intimate and/or suggestive romantic relations.
Even though most of the 'Dubious' fics get categorized as 'Young Adult', please don't confuse the tag as being only profanity. Bad words are just simply the easiest thing to search for.
As of writing, there are nearly 23,000 Mature Fics and 66,000+ Teen Fics. I do not have the time to review all of them to assign appropriate tags, but will make an effort to categorize most.
If you find a fic that you think should have its rating adjusted, please let me know! I can't do it all on my own.
On the story pages (while logged in), you can submit a revision post.

OPDS stands for "Open Publication Distribution System," which is a fancy way of saying it's a special format for sharing books.

If you have an OPDS-compatible eReader or app, you can browse fimfetch directly!

https://fimfetch.net/opds
				

If you want to enable viewing mature fictions, add the mature flag to the url like this:

https://fimfetch.net/opds?mature
				

Also, if you have a user login, you can access your bookshelves and default search options (including mature preferences) using your user key!

You're not logged in right now, but if you were, you'd be able to see your user key here or in your library.

When using a personal key to access the service, all searches are filtered using your personal search defaults, and any fictions downloaded are added to your private mobile library.
Don't share this link with anyone you don't trust, and likewise don't use links from other people you don't trust.

Tested with a number of android eReaders, but there's a chance that something might not work right. Please feel free to contact me about it!

FBReader:

Fimfetch generates multiple formats for your reading pleasure, including text files and original html for oldschool colectors in addition to epub and mobi for mobile readers and a tidied-up html for cached viewing.

One key feature I knew for sure I wanted in this project was to automatically generate and have available for download mobi files, which is the file format that Kindle E-Readers use.
E-Ink Readers are awesome, by the way.

My personal favorite feature of the content generators I wrote, however, are the Epub files before the mobi are generated. I have worked to iron out xml syntax errors and formatting tags in order to allow fics to be read on stringy ereaders (I'm looking at you, Apple!), have changed how the title page works vs fimfiction's format including putting the title, author, rating tags, wordcount, and description on the title page, and have also added a bit of fancy magic that embeds externally linked images directly into the file! Now you don't need your reader to be connected to the internet to enjoy graphics!

I love numbers, don't you?

Time to read numbers are based on an average reading speed of 250 words per minute, and 14 hours per day.
