Issues with adding tags -- 

-- can we not use more than ten tags?  I know I used to be able to add 12 or 14 per book.  
-- some tags not allowed?  I tried multiple times to add ' US Marshall Service'  as the first tag. Then later tried to add ' drug use'. Neither of these will 'save'. 

I had 312 tags and just added another one a few minutes ago making it 313, with no probems.

I've found certain words or letter combinations won't go through. I played with your tag, and found  I could add "Marshall Service"  (British spelling) "Marshal Service" (American spelling) and "United States Marshal Service" / "United States Marshall Service", if that helps.

"Drug abuse" works, but not "Drug use".

Play with your wording a bit, and you can often find something that will work. There's no limit to how many tags you can add.

Thanks, Patty....just some weird things going on this week with some functions. 

today another tag issue......... Won't let me add 'Queen Elizabeth I' as a tag!!

More tag issues....won't let me add ' Women's Movement' or ' right to vote'. 

Several years ago, a bunch of problem words were blocked, including swear words and insults. I find that sometimes if a letter combination is part of a blocked word, I have to find a work-around.

"right 2 vote" works

"Women's movement" worked for me

Queen Elizabeth 1 (with a numeral) and Queen Elizabeth the First both work

If you have tag with 2 or more words that won't "take", try the words individually, and you'll see which word is causing the problem.Then you can figure out an alternate tag.

Thanks, Patty. Will try the suggestions.
