This is not currently possible, partially also because "last" is not well-defined -- bibbase does not know whether you add new entries in the front or the back (or the middle) of your bibtex file. What you can do, however, is to use a filter, e.g., if you add "&filter=year:2016" to your URL it should only list papers from 2016. This works on any field, so if you really wanted to, you could go in and edit your bibtex file to mark the ones you want to list with a special field (e.g., show={1}), and then filter on that.

A CSS really only makes sense when you embed your BibBase listing in your own page. I see that you are embedding it in https://scc.okstate.edu/publications. You need to add the CSS file directly to the head of the HTML of that page, like you are doing with the other CSS files that are already referenced there.

We don't test with IE very much, and it might take a while until we get to this. But I don't think you need to worry too much about this, because less then 5% of all visitors to BibBase pages actually use IE or Edge:

That's just a style decision. The default theme/CSS style hide the bibbase_icon_text elements and show the bibbase_icon elements instead. To show the text instead of the icons you can either change the CSS rules for these CSS classes accordingly, or use one of the predefined themes that already use that, e.g.:

http://bibbase.org/show?bib=http%3A%2F%2Fclulab.cs.arizona.edu%2Fpapers%2Fclulab.bib&theme=side

The filter value is a regular expression. So "Lau[^a-z]" should work for you.

There is a suffix on the URL "&msg=embed". Just remove that and the message will no longer show. It should have been removed already when using any of snippets in that message.

There were two problem: the field name to filter authors on is `authors` (not author), but also, it can be very tricky to use the right syntax when using zotero, because some of the arguments need to be encoded, so that BibBase doesn't interpreted them but passes them on to Zotero (e.g., format). But others, the ones for BibBase, must not be. In your case you were using an encoded representation of the ampersand, which meant it was forwarded to Zotero, but it needs to be interpreted by BibBase.

This link works:

Similarly, to filter by year you would use, e.g.:

http://bibbase.org/show?bib=https://api.zotero.org/groups/986230/items?key=toLYm4ZmsffGetBPhyaSe8eU%26format=bibtex%26limit=100&filter=year:2007
